Problem: Keith Jarrett (born May 8, 1945) is an American jazz and classical music pianist. Jarrett started his career with Art Blakey, moving on to play with Charles Lloyd and Miles Davis. Since the early 1970s he has enjoyed a great deal of success as a group leader and a solo performer in jazz, jazz fusion, and classical music. His improvisations draw from the traditions of jazz and other genres, especially Western classical music, gospel, blues, and ethnic folk music.

In 1983, at the suggestion of ECM head Manfred Eicher, Jarrett asked bassist Gary Peacock and drummer Jack DeJohnette, with whom he had worked on Peacock's 1977 album Tales of Another, to record an album of jazz standards, simply titled Standards, Volume 1. Two more albums, Standards, Volume 2 and Changes, both recorded at the same session, followed soon after. The success of these albums and the group's ensuing tour, which came as traditional acoustic post-bop was enjoying an upswing in the early 1980s, led to this new standards trio becoming one of the premier working groups in jazz, and certainly one of the most enduring, continuing to record and tour for more than 25 years. The trio has recorded numerous live and studio albums consisting primarily of jazz repertory material.  The Jarrett-Peacock-DeJohnette trio also produced recordings that consist largely of challenging original material, including 1987's Changeless. Several of the standards albums contain an original track or two, some attributed to Jarrett, but most are group improvisations. The live recordings Inside Out and Always Let Me Go (released in 2001 and 2002 respectively) marked a renewed interest by the trio in wholly improvised free jazz. By this point in their history, the musical communication among these three men had become nothing short of telepathic, and their group improvisations frequently take on a complexity that sounds almost composed. The standards trio undertakes frequent world tours of recital halls (the only venues in which Jarrett, a notorious stickler for acoustics, will play) and is one of the few truly successful jazz groups to play both straight-ahead (as opposed to smooth) and free jazz.  A related recording, At the Deer Head Inn (1992), is a live album of standards recorded with Paul Motian replacing DeJohnette, at the venue in Delaware Water Gap, Pennsylvania, 40 miles from Jarrett's hometown, where he had his first job as a jazz pianist. It was the first time Jarrett and Motian had played together since the demise of the American quartet sixteen years earlier.

how did it challenge the original material?

Question:
Robert Matthew Van Winkle was born in Dallas, Texas, on October 31, 1967. Van Winkle has never known his biological father; he was given the family name of the Dutch man his mother was married to at the time of his birth. When Van Winkle was four, his mother divorced. Afterward, he grew up moving between Dallas and Miami, where his new stepfather worked at a car dealership.
After almost non-stop touring for the previous three years, Ice took a break from music in 1993 and began competing in jet skiing (becoming the 6th best jet ski racer in the world and obtaining sponsorship from Kawasaki) as well as resuming Motocross racing.  By 1994, Ice received less publicity and became removed from the public spotlight. After becoming more interested with the Rastafari movement, Ice became a vegetarian, grew dreadlocks and talked more openly about smoking cannabis. On March 22, 1994, Ice released his second studio album, Mind Blowin'. Reviews were unfavorable. Entertainment Weekly reviewer James Bernard called the album "more clunky than funky". Rolling Stone reviewer Danyel Smith praised the song "Get Loose" as "snappy", writing that although the lyrics are "inane", "the song is a thumping party, one of the few places where Ice loosens up. He sounds solid at the beginning of 'The Wrath' as well ... In 'Now and Forever,' a wet dream kind of song, Ice goes back to goofy lyrics." Allrovi reviewer Stephen Thomas Erlewine wrote that "There isn't a single moment that establishes a distinct musical identity, and the whole thing is rather embarrassing." Primus bassist Les Claypool stated in response to Ice's cannabis-oriented lyrics: "That's all fine and dandy and cute, but it could be misconstrued and manipulated by the wrong people." When asked about the drug oriented sound years later, Vanilla Ice said "A lot of the record is drug oriented because I was doing a lot of drugs at the time". Shortly afterward, SBK went bankrupt.  At around this time, Ice began using ecstasy, cocaine and heroin. During periods of heavy drug use, Ice received many tattoos from artist acquaintances. According to Ice, he "was in [his] binge days. [He] didn't even realize how many [he] was getting". Ice attempted suicide with a heroin overdose on July 4, 1994 but was revived by his friends. After being revived, Ice decided that it was time to change his lifestyle. As a symbol of his attempt to begin anew, he got a tattoo of a leaf on his stomach. After expanding his Mind Blowin tour overseas in 1995, Ice sold his estate in California and took a break from music, rather focusing on motocrossing and jet skiing in Florida. By the summer Ice was the world's No. 6-ranked sit-down Jet Ski racer, competing nearly every weekend and earning a Kawasaki sponsorship.  Uncertain about his future career, Ice studied real estate and started working on the side renovating and selling houses. In late 1995, Ice set up a recording studio in Miami and joined a grunge band, Pickin Scabz. The name was set to reflect Ice's career and how he was healing from his suicide attempt and that he was now "picking up the pieces". Ice expressed an interest in performing hip hop-influenced rock music, but found that the band was unable to produce the sound he was looking for. In 1996, longtime associate and friend Monte Lipman signed Ice as an artist for Universal Republic Records. He did guest vocals with no stage name for the song "Boom" by Bloodhound Gang on their CD One Fierce Beer Coaster.
