Phalanx was a jazz quartet featuring guitarist James "Blood" Ulmer, drummer Rashied Ali, tenor saxophonist George Adams, and bassist Sirone.
They released three albums: Got Something Good for You (1986), Original Phalanx (1987) and In Touch (1988).
[1] They've been described as "an ad-hoc supergroup that thrived and disappeared."
While the quartet is said to have moved on after the 1980s, they played a show at the Museum of Natural History in 1991.
