You probably know John Sinclair’s name from his status as a legendary Detroit activist and MC5 manager. But he also worked with trumpeter Charles Moore to put on a wide variety of Detroit Artists Workshop shows that highlighted some of the best local jazz talent. This new compilation gives us a glimpse of the sweet sounds that went down over the years. Some familiar names here (Donald Byrd playing a marvelously moody version of “Cristo Redentor”) and some less familiar names (organist Lyman Woodard sounds fantastic).
