Background: Jerry Fulton Cantrell Jr. (born March 18, 1966) is an American musician who is best known as the founder, lead guitarist, co-lead vocalist and main songwriter for the rock band Alice in Chains. The band rose to international fame in the early 1990s during Seattle's grunge movement, and is known for its distinctive vocal style, and the harmonized vocals between Cantrell and Layne Staley (and later Cantrell and William DuVall). Cantrell started to sing lead vocals on Alice in Chains' 1992 EP Sap. After Staley's death in 2002, Cantrell took the role of Alice in Chains' lead singer on most of the songs from the band's two albums without Staley, Black Gives Way to Blue (2009) and The Devil Put Dinosaurs Here (2013), with DuVall harmonizing with him in the new songs and singing Staley's vocals in the old songs.
Context: Cantrell has been most famously seen playing a G&L Guitars' Rampage model. The two models most closely identified with Cantrell are instruments manufactured in the 1980s. They feature a maple body, maple neck and ebony fingerboard. The bridge is a Kahler Tremolo as opposed to a Floyd Rose tremolo which was commonly seen on instruments made throughout the 1980s and 90s. The guitars feature a single-bridge humbucker wired to a volume pickup.  G&L Guitars makes two Jerry Cantrell Signature guitars available to the general public for purchase. The first is a Rampage model which is very similar to the instrument most closely identified with Cantrell, known as the "Blue Dress Rampage" for having an image of a vintage pin-up girl wearing a blue dress, which Cantrell taped to the top of his first guitar. The second is a guitar called the 'Superhawk'. This guitar features a fixed bridge and the addition of a neck pickup.  Cantrell used the original "Blue Dress" guitar on the music videos for "Man in the Box", "We Die Young", "Sea of Sorrow", "Grind", and "Again". The guitar can also be seen in the movie Singles. In 2011, Cantrell told that he had to retire the guitar due to a hairline crack from the neck all the way through the back of the body. Before that, he had never gone on tour without it.  Apart from his signature G&L Guitars, Cantrell has also been seen playing a Les Paul and a Telecaster  Cantrell used a variety of amplifiers such as those made by Bogner, Mesa Boogie and Marshall throughout his career. He has most recently been using a signature amp called the, 'JJ100' made for him by Friedman Amplification.

Problem: Background: 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.
Context: 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."
Question: What other aspects of the centenary commemoration are notable?
