Live at Sweet Basil is a live album by jazz composer, arranger, conductor and pianist Gil Evans, and recorded by King Records (Japan) in New York in 1984. It featured Evans with his Monday Night Orchestra, which included George Adams, Howard Johnson, and Lew Soloff. The album was originally released in the US on the Gramavision label.
Gil Evans' Monday night marathon sessions at "Sweet Basil Jazz Club" started as a workshop in April 1983, to select players and do rehearsals in preparation for his Japan tour in May. The performances at the workshop drew attention and a good reputation, and the club asked Evans to continue to perform periodically on Mondays after the Japan tour.
AllMusic awarded the album 2 stars, stating, "It may not have been "cool," but it was most assuredly great jazz".
