SOUNDTRACK

Electric Flag, “Old Glory: The Best of Electric Flag,” Legacy/Columbia ** 1/2. Featuring guitarist Mike Bloomfield and singer Nick Gravenities, this group created a stir with its bluesy blend of jazz-rock. Bloomfield left after one terrific 1968 album, “A Long Train Comin’.” The follow-up, “The Electric Flag,” was terrible and the group flamed out. Fortunately, “A Long Train Comin’ ” dominates this collection, which also includes some so-so previously unreleased material.
