Rudy Williams was a journeyman sax player who stylistically crossed between swing and bebop.  The son of legendary/notorious bandleader Fess Williams and the cousin of Charles Mingus, Williams is here heard on alto sax with a pickup group put together by Baron Timme Rosenkrantz in 1939 (with Don Byas, Tyree Glenn, Rex Stewart, Russell Procope, Billy Kyle, Walter Page and Jo Jones), the Savoy Sultans (his regular band from 1937-1941 or so), a Don Byas group (with Charlie Shavers and Clyde Hart), Tadd Dameron's Sextet (with Fats Navarro, Allan Eager, Kenny Clarke and Curly Russell), Bennie Green's Sextet (on baritone, with Teddy Brannon and Lockjaw Davis) and the Howard McGhee Korean All-Stars (on tenor, with J.J. Johnson and Skeeter Best).
