Play jazz: "The Days Of Wine And Roses" – Oscar Peterson improvisation on the theme by Henry Mancini is included in the album "We Get Requests", recorded in 1964 by the Oscar Peterson trio (Oscar Peterson – piano, Ray Brown - contrabass, Ed Thigpen - drums) and is one of the best jazz improvisations on this theme.
Big band refers to a jazz group of 10 or more musicians, usually featuring at least three trumpets, two or more trombones, four or more saxophones, and a rhythm section of accompanists playing some combination of piano, guitar, bass, and drums. Big-band music as a concept for music fans is identified most with the swing era, though there were large, jazz-oriented dance bands before the swing era of the 1930s and 1940s and large jazz-oriented bands after the swing era.
