Answer the question at the end by quoting:

John Milton Cage Jr. (September 5, 1912 - August 12, 1992) was an American composer and music theorist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives.
In 2012, amongst a wide range of American and international centennial celebrations, an eight-day festival was held in Washington DC, with venues found notably more amongst the city's art museums and universities than performance spaces. Earlier in the centennial year, conductor Michael Tilson Thomas presented Cage's Song Books with the San Francisco Symphony at Carnegie Hall in New York. Another celebration came, for instance, in Darmstadt, Germany, which in July 2012 renamed its central station the John Cage Railway Station during the term of its annual new-music courses. At the Ruhrtriennale in Germany, Heiner Goebbels staged a production of Europeras 1 & 2 in a 36,000 sq ft converted factory and commissioned a production of Lecture on Nothing created and performed by Robert Wilson. Jacaranda Music had four concerts planned in Santa Monica, California, for the centennial week. John Cage Day was the name given to several events held during 2012 to mark the centenary of his birth.  A 2012 project was curated by Juraj Kojs to celebrate the centenary of Cage's birth, titled On Silence: Homage to Cage. It consisted of 13 commissioned works created by composers from around the global such as Kasia Glowicka, Adrian Knight and Henry Vega, each being 4 minutes and 33 seconds long in honor of Cage's famous 1952 opus, 4'33''. The program was supported by the Foundation for Emerging Technologies and Arts, Laura Kuhn and the John Cage Trust.  In a homage to Cage's dance work, the Bill T. Jones/Arnie Zane Dance Company in July 2012 "performed an engrossing piece called 'Story/Time'. It was modeled on Cage's 1958 work 'Indeterminacy', in which [Cage and then Jones, respectively,] sat alone onstage, reading aloud ... series of one-minute stories [they]'d written. Dancers from Jones's company performed as [Jones] read."

What was the centenary commemoration?

several events held during 2012 to mark the centenary of his birth.

Some context: Nathan Jonas "Joey" Jordison (born April 26, 1975), is an American musician, songwriter, record producer and multi-instrumentalist, best known for his work as the former drummer and co-songwriter for the American heavy metal band Slipknot as well as guitarist in the American horror punk band Murderdolls. Jordison played in Slipknot since their formation in 1995 until his departure from the band in December 2013. He was the drummer and founder of the American heavy metal band Scar the Martyr which formed in 2013 and disbanded in 2016.
On November 28, 1995, Mark Anthony Cadavos approached Jordison while he was working, offering him a position in a new project called The Pale Ones. Intrigued and at a point where he was "lost", Jordison attended rehearsals at Anders Colsefini's basement and immediately wanted to be part of this new band. Speaking of this moment he said, "I remember trying so hard not to smile, so I didn't look like I wanted to join, I remained poker-faced, but I thought they ruled." A lot of Slipknot's early development was discussed by band members while Jordison worked night shifts at Sinclair's garage. Of the eventual nine members, Joey was the third to join the band. Slipknot would become pioneers to the New Wave of American Heavy Metal. Jordison is accompanied by two custom percussionists, giving their music a feel that Rolling Stone touted as "suffocating".  Each member of Slipknot is assigned a number; Joey was assigned "#1" because drums are recorded first. Joey has produced one album with Slipknot: 2005 live album 9.0: Live. In August 2008, Jordison broke his ankle and Slipknot had to cancel some of its English tour dates. On August 22, 2009, Jordison was taken to the emergency room for a burst appendix, less than an hour before he was to take the stage for Auburn, Washington's KISW Pain in the Grass concert. As a result, Slipknot canceled following shows in August and September, to give Jordison time to recover.  On December 12, 2013, Slipknot announced through their official website that Jordison had left the band, citing personal reasons for his departure. In response, Jordison released a statement insisting that he had in fact been fired from the band and stated that Slipknot "has been my life for the last 18 years, and I would never abandon it, or my fans".  After years of both sides being silent and evasive as to the reasons for his leaving the band, Jordison revealed in June 2016 that he suffered from transverse myelitis, a neurological disease which cost him the ability to play the drums toward the end of his time with Slipknot.
What type of music was Slipknot?
A: Slipknot would become pioneers to the New Wave of American Heavy Metal.

IN: Benjamin Edward Meara Stiller was born on November 30, 1965 in New York City. His father, comedian and actor Jerry Stiller, is from a Jewish family that emigrated from Poland and Galicia in Central Europe. His mother, actress and comedian Anne Meara, who was from an Irish Catholic background, converted to Reform Judaism after marrying his father. While the family was "never very religious", they celebrated both Hanukkah and Christmas, and Stiller had a Bar Mitzvah.

Stiller had a few minor roles in the early 1990s, in films such as Stella, Highway to Hell and in a cameo, The Nutt House. In 1992, Stiller was approached to direct Reality Bites, based on a script by Helen Childress. Stiller devoted the next year and a half to rewriting the script with Childress, fundraising and recruiting cast members for the film. It was eventually released in early 1994, directed by Stiller and featuring him as a co-star. The film was produced by Danny DeVito, who would later direct Stiller's 2003 film Duplex and produce his 2004 film Along Came Polly.  Reality Bites debuted as the highest-grossing film in its opening weekend and received mixed reviews.  Stiller joined his parents in the family film Heavyweights (1995), in which he played two roles, and then had a brief uncredited role in Adam Sandler's Happy Gilmore (1996). Next, he had lead roles in If Lucy Fell and Flirting with Disaster, before tackling his next directorial effort with The Cable Guy, which starred Jim Carrey. Stiller once again was featured in his own film, as twins. The film received mixed reviews, but was noted for paying the highest salary for an actor up to that point, as Carrey received $20 million for his work in the film. The film also connected Stiller with future Frat Pack members Jack Black and Owen Wilson.  Also in 1996, MTV invited Stiller to host the VH1 Fashion Awards. Along with SNL writer Drake Sather, Stiller developed a short film for the awards about a male model known as Derek Zoolander. It was so well received that he developed another short film about the character for the 1997 VH1 Fashion Awards and finally remade the skit into a film.
