'COMM:MusicMatch_Bio:ENG'                           ('One of the first art-rock bands to experiment with classical forms and '
 'fusion, the Nice was an early vehicle for the talents of keyboard virtuoso '
 'Keith Emerson, who plundered Mozart, Sibelius, and Tchaikovsky for his '
 'extended rock instrumental forays. The group began as the backing band for '
 "British soul singer P.P. Arnold and also featured guitarist David O'List, "
 'drummer Brian "Blinky" Davison, and bassist Lee Jackson. In October 1967, '
 'only two months after formation, the group split from Arnold, christened '
 'itself the Nice, and released a single called "The Thoughts of Emerlist '
 'Davjack," which became the title track of their 1968 debut album. The Nice '
 'quickly built a reputation as an exciting, theatrical live band thanks to '
 'Emerson, who dressed in gold lame, hurled knives into his Hammond organ to '
 "produce strange sounds, and mimed masturbation onstage. Emerson's antics "
 'spawned controversy with Ars Longa Vita Brevis, which contained a cover of '
 'Leonard Bernstein\'s West Side Story song "America." The Nice performed it '
 'at the Royal Albert Hall while burning an American flag, and Bernstein '
 "subsequently attempted to stop the song's release in the U.S. Emerson had "
 'emerged as the star of the group, both in terms of instrumental skill and '
 "showmanship, and the fed-up O'List had departed the group by the time of the "
 "album's release to join Roxy Music. Nice and Five Bridges Suite became big "
 'hit albums in Britain, but the group never broke through in America. In '
 '1969, Emerson met Greg Lake, then with King Crimson, on a U.S. tour, and '
 'broke up the Nice in frustration in 1970 due to its lack of success. He, '
 'Lake, and drummer Carl Palmer formed the much more popular Emerson, Lake and '
 "Palmer, which expanded on Emerson's innovations with the Nice. The remaining "
 'Nice members went on to several short and/or unsuccessful stints with other '
 'groups before fading away. ')
