Neil's Blues is an original composition by alto saxophonist Frank Morgan, first recorded on March 31, 1955, at The Crescendo club in Los Angeles for the album Gene Norman Presents Frank Morgan on GNP Crescendo. The tune is a bop-inflected blues head that showcases Morgan's deeply rooted bebop sensibility, featuring a written melody for alto saxophone set against the swinging energy of a West Coast jazz septet. The session captured Morgan alongside an exceptional group of musicians, including trumpeter Conte Candoli, tenor saxophonist Wardell Gray (in what would be among his final recordings before his death later that year), pianist Carl Perkins, guitarist Howard Roberts, bassist Leroy Vinnegar, and drummer Larance Marable. The arrangement opens with a piano introduction before presenting the head, followed by extended solo sections with multi-chorus improvisations and four-bar trading passages that give the performance a structured yet expansive character. Neil's Blues remains a deep cut in the jazz repertoire, closely tied to Morgan's brief but significant early recording period before addiction derailed his career for nearly three decades. The tune resurfaced through reissues of the original album, but it has not been widely covered or adopted as a standard by other artists.
