Samuel Carthorne Rivers was an American jazz musician and composer. Though most famously a tenor saxophonist, he also performed on soprano saxophone, bass clarinet, flute, harmonica, piano and viola.

Anthony Tillmon Williams was an American jazz drummer. Williams first gained fame as a member of Miles Davis' "Second Great Quintet," and later pioneered jazz fusion with Davis' group and his own combo, the Tony Williams Lifetime. In 1970, music critic Robert Christgau described him as "probably the best drummer in the world." Williams was inducted into the Modern Drummer Hall of Fame in 1986.
