Input: Question: Which American composer who were pioneers in Minimal music was born first? Passage 1:In 1950, Yost posted career-highs with a .295 batting average and a .440on-base percentage. In 1951 he led the American League with 36doubles and produced a career-high 65 runs batted in. He earned a place as a reserve player for the American League team in the 1952 All-Star Game. Between August 30, 1949 and May 11, 1955, Yost played in 829 consecutive games for the Senators, the ninth longest consecutive game streak in major league history. Yost's home run totals were diminished by having to play his home games in Washington's cavernous Griffith Stadium. Between 1944 and 1953, he hit only 3 home runs at home while hitting 52 home runs on the road.
Passage 2:Minimal music is a form of art music that employs limited or minimal musical materials. In the Western art music tradition, the American composers La Monte Young, Terry Riley, Steve Reich, and Philip Glass are credited with being among the first to develop compositional techniques that exploit a minimal approach. It originated in the New York Downtown scene of the 1960s and was initially viewed as a form of experimental music called the New York Hypnotic School. As an aesthetic, it is marked by a non-narrative, non-teleological, and non-representational conception of a work in progress, and represents a new approach to the activity of listening to music by focusing on the internal processes of the music, which lack goals or motion toward those goals. Prominent features of the technique include consonant harmony, hypnotic rhythmic pulses or steady drones, stasis or gradual transformation, and often reiteration of musical phrases or smaller units such as figures, motifs, and cells. It may include features such as additive process and phase shifting. Phase-shifting leads to what has been termed phase music. Minimal compositions that rely heavily on process techniques that follow strict rules are usually described as process music.
Passage 3:The Sugababes performed "Caught in a Moment" on 12 August 2004 at the Bristol International Balloon Fiesta, which is one of Europe's biggest balloon festivals. The third-line up of the band, consisting of Buchanan, Range and Amelle Berrabah, performed "Caught in a Moment" at the Sheffield City Hall in March 2006 as part of their tour in support of Taller in More Ways (2005). According to Dave Simpson of The Guardian, the performance suggested that Berrabah "could trigger an unlikely shift into soul" for the group. The trio performed "Caught in a Moment" at the 100 Club, London on 3 October 2006 as part of a gig, which was in promotion of Overloaded: The Singles Collection. They performed the song as part of the Overloaded tour, and were seated on stools in the centre of the stage. With regard to their performance on 13 April 2007 at the Wembley Arena, London, Ben Rawson-Jones of Digital Spy commented: "Their epiphanic beauty was fully realised with the fragile, emotive nature of Heidi's voice and Keisha's powerful singing". "Caught in a Moment" appeared in the set list for the group's 2008 Change Tour. According to The Journals Kat Keogh, their performance at the Newcastle City Hall "displayed a confident shift from moody pop princesses to sassy Supremes-style harmony".
