Problem: Background: Three Days Grace is a Canadian rock band formed in Norwood, Ontario in 1997. Based in Toronto, the band's original line-up consisted of guitarist and lead vocalist Adam Gontier, drummer and backing vocalist Neil Sanderson, and bassist Brad Walst. In 2003, Barry Stock was recruited as the band's lead guitarist, making Three Days Grace a four-member band. In 2013, Gontier left the band and was replaced by My Darkest Days' vocalist Matt Walst, who is also bassist Brad Walst's brother.
Context: Three Days Grace has its origins in a five-piece band called "Groundswell", formed in Norwood, Ontario, in 1992. Groundswell released one full-length album, Wave of Popular Feeling. The band's line-up consisted of lead vocalist Adam Gontier, drummer Neil Sanderson, bassist Brad Walst, lead guitarist Phil Crowe, and rhythm guitarist Joe Grant. Most of the members were attending high school when the band formed. By the end of 1995, the band had broken up.  In 1997, Gontier, Sanderson, and Walst regrouped as "Three Days Grace". According to Gontier, the name refers to a sense of urgency, with the question being whether someone could change something in their life if they had only three days to make a change. Once in Toronto, the band became acquainted with local producer Gavin Brown. The band gave him several years of material which they had created, and he "...picked out what he called 'the golden nuggets'", according to Gontier. Brown and the band polished the songs, and created a demo album, which they gave to EMI Music Publishing Canada. The record label wanted to hear more material, and with Brown producing, the band created the song, "I Hate Everything About You", which attracted the interest of several record labels. The band was soon signed to Jive Records after being sought out by the company's president.  The band moved to Long View Farm, a studio in North Brookfield, Massachusetts, to record their debut album. The self-titled album was finished in Woodstock, New York and released on July 22, 2003.  It was met with mixed to favourable reviews. Dave Doray of IGN said of the album, "Mistakes? There's not many." Allmusic reviewer Heather Phares said that on Three Days Grace, "the band's focus and adherence to alt-metal's formulas - coupled with tight songwriting and some unexpectedly pretty choruses - results in a strong tracks  [sic] that are more memorable than the work of many of their peers". She did criticize the album for its simplicity, concluding, "Three Days Grace are definitely one of the most accessible alt-metal bands of the 2000s; they just need to add some more distinctiveness to their sound."  To support the eponymous album, in 2003 Three Days Grace released its first single, "I Hate Everything About You" (the song whose demo had gotten the band its record deal). The song received heavy airplay and rapidly became a widely recognizable song, and was labelled as the band's "breakout hit". After Barry Stock joined as lead guitarist in late 2003, Three Days Grace toured continuously and extensively for nearly two years in support of their major label debut. The album peaked at number nine on the Canadian Albums Chart and number 69 on the Billboard 200, and was certified platinum in the U.S. by the RIAA in December 2004 and double platinum in Canada by the CRIA.
Question: Why did they break up?
Answer: Most of the members were attending high school

Background: Lester Willis Young (August 27, 1909 - March 15, 1959), nicknamed "Pres" or "Prez", was an American jazz tenor saxophonist and occasional clarinetist. Coming to prominence while a member of Count Basie's orchestra, Young was one of the most influential players on his instrument. In contrast to many of his hard-driving peers, Young played with a relaxed, cool tone and used sophisticated harmonies, using what one critic called "a free-floating style, wheeling and diving like a gull, banking with low, funky riffs that pleased dancers and listeners alike". Known for his hip, introverted style, he invented or popularized much of the hipster jargon which came to be associated with the music.
Context: In 1933 Young settled in Kansas City, where after playing briefly in several bands, he rose to prominence with Count Basie. His playing in the Basie band was characterized by a relaxed style which contrasted sharply with the more forceful approach of Coleman Hawkins, the dominant tenor sax player of the day. One of Young's key influences was Frank Trumbauer, who came to prominence in the 1920s with Paul Whiteman and played the C-melody saxophone (between the alto and tenor in pitch).  Young left the Basie band to replace Hawkins in Fletcher Henderson's orchestra. He soon left Henderson to play in the Andy Kirk band (for six months) before returning to Basie. While with Basie, Young made small-group recordings for Milt Gabler's Commodore Records, The Kansas City Sessions. Although they were recorded in New York (in 1938, with a reunion in 1944), they are named after the group, the Kansas City Seven, and comprised Buck Clayton, Dicky Wells, Basie, Young, Freddie Green, Rodney Richardson, and Jo Jones. Young played clarinet as well as tenor in these sessions. Young is described as playing the clarinet in a "liquid, nervous style."  As well as the Kansas City Sessions, his clarinet work from 1938-39 is documented on recordings with Basie, Billie Holiday, Basie small groups, and the organist Glenn Hardman. Billie and Lester met at a Harlem jam session in the early 30s and worked together in the Count Basie band and in nightclubs on New York's 52nd St. At one point Lester moved into the apartment Billie shared with her mother, Sadie Fagan. Holiday always insisted their relationship was strictly platonic. She gave Lester the nickname "Prez" after President Franklin Roosevelt, the "greatest man around" in Billie's mind. Playing on her name, he would call her "Lady Day." Their famously empathetic classic recordings with Teddy Wilson date from this era.  After Young's clarinet was stolen in 1939, he abandoned the instrument until about 1957. That year Norman Granz gave him one and urged him to play it (with far different results at that stage in Young's life--see below).
