Background: Bela Fleck and the Flecktones is an American band that combines jazz and bluegrass music. The band's name is a play on 1960s rock band Dick Dale and the Del-Tones. The Flecktones formed in 1988 when Bela Fleck was invited to perform on the PBS TV series The Lonesome Pine Specials. The original members were Fleck on banjo, Victor Wooten on bass guitar, his brother Roy Wooten on Drumitar, and Howard Levy on harmonica and keyboards.
Context: In April 1997, the Flecktones became a quartet again, as they added saxophone player Jeff Coffin to the mix. Coffin would remain in the band from 1997 until 2008. In June 1997, the Flecktones opened for The Dave Matthews Band. In July the Flecktones toured Europe and sat in on the second set of a Phish show in Lyon, France. This marked the second and final time that the Flecktones played with Phish.  In June 1998, the Flecktones released their sixth album, and fifth studio album, Left of Cool. Left of Cool represents a switch from previous Flecktones albums, as the band, according to critic Terri Horak "jettisoned their self-imposed rule to only record what could be duplicated on live instruments." In July 2000, the Flecktones released their eighth album, Outbound. Outbound is another studio album, and again the Flecktones' philosophy with this album was to do something different from everything they had done before. What makes Outbound unique is the way in which the Flecktones recorded the album. The quartet recorded each track on the album, then invited guest musicians to overdub vocals or instrumentation. Outbound guests include: Jon Anderson from Yes, Shawn Colvin and John Medeski, of Medeski, Martin and Wood, to name a few. The album earned the Flecktones the Grammy for Best Contemporary Jazz Album that year.  Live at the Quick, which was also released as a DVD, is the band's ninth album, and second live album. For fans of live Flecktones, this album, like Live Art, successfully captured the sound and feel of the Flecktones in concert. Little Worlds, the band's tenth album was released on August 12, 2003. Like previous Flecktones' albums, Little Worlds features a slew of musical guests, from Sam Bush on mandolin, Derek Trucks on guitar and even former New York Yankee and guitarist Bernie Williams works his way into a track. Little Worlds was released as a 3-CD album, but for the less committed listener, the band also released Ten From Little Worlds, which includes ten songs off of the original 3-CD Little Worlds.  In February 2006, the band released their eleventh album, The Hidden Land. As with every Flecktones album, they needed to change something from their last album. For The Hidden Land, the Flecktones didn't want any guest musicians. "'The truth is, the last few records are not what we are,' Fleck said. 'Obviously, we loved playing with those musicians, but if you keep on doing it, you become a gathering point rather than a group with its own identity.'" For the Flecktones to keep moving forward, they felt their music had to get back to the roots of the quartet. After spending much of the year apart, the Flecktones came together in 2008 to release a holiday album, Jingle All the Way.
Question: Who is part of this quartet?
Answer: the Flecktones became a quartet again, as they added saxophone player Jeff Coffin to the mix.

Background: Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television judge. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson under her birth name in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations and she subsequently began working with producers Glen Ballard, Dr. Luke, and Max Martin.
Context: Perry completed her General Educational Development (GED) requirements at age 15, during her freshman year of high school, and left Dos Pueblos High School to pursue a musical career. She briefly studied Italian opera at the Music Academy of the West in Santa Barbara. Her singing caught the attention of rock artists Steve Thomas and Jennifer Knapp from Nashville, Tennessee, who brought her there to improve her writing skills. In Nashville, she started recording demos and learned how to write songs and play guitar. After signing with Red Hill Records, Perry recorded her debut album, a gospel record titled Katy Hudson. She released the album on March 6, 2001, and went on tour that year as part of Phil Joel's Strangely Normal Tour while also embarking on other performances of her own in the United States. Katy Hudson received positive reviews from critics, though was commercially unsuccessful and sold an estimated 200 copies before the label ceased operations in December. Transitioning from gospel music to secular music, Perry started writing songs with producer Glen Ballard, and moved to Los Angeles at age 17. In 2003, she briefly performed as Katheryn Perry to avoid confusion with actress Kate Hudson. She later adopted the stage name Katy Perry, using her mother's maiden name.  In 2004, Perry signed to Ballard's label, Java, which was then affiliated with The Island Def Jam Music Group. She began work on a solo record, but the record was shelved after Java was dropped. Ballard then introduced Perry to Tim Devine, an A&R executive at Columbia Records, and she was signed as a solo artist. Over the course of the next two years, Perry wrote and recorded material for her Columbia debut, and worked with songwriters including Desmond Child, Greg Wells, Butch Walker, Scott Cutler, Anne Preven, The Matrix, Kara DioGuardi, Max Martin and Dr. Luke. In addition, after Devine suggested that songwriting team The Matrix become a "real group", Perry recorded with them. Perry was dropped from Columbia in 2006 as her record neared completion. After the label dropped her, she worked at an independent A&R company called Taxi Music.  Perry had minor success prior to her breakthrough. One of the songs she had recorded for her album with Ballard, "Simple", was featured on the soundtrack to the 2005 film The Sisterhood of the Traveling Pants. She provided backing vocals on Mick Jagger's song "Old Habits Die Hard", which was included on the soundtrack to the 2004 film Alfie. In September 2004, Blender named Perry "The Next Big Thing". She recorded background vocals on P.O.D.'s single "Goodbye for Now" and was featured at the end of its music video in 2006. That year, Perry also appeared in the music video for "Learn to Fly" by Carbon Leaf, and played the love interest of her then-boyfriend, Gym Class Heroes lead singer Travie McCoy, in the band's music video for "Cupid's Chokehold".
