Requiem is a live album by bassist and composer William Parker's Bass Quartet featuring Charles Gayle, which was recorded at the Vision Festival in New York in 2004 and released on the Italian Splasc(H) label.

[1] The All About Jazz review stated "The group's significance stemmed from the stylistic lineage evident from Grimes to Silva to Sirone to Parker and the addition of guest saxophonist Charles Gayle added a wrinkle, an uncommon hierarchy with a horn playing over four bassists".
