Blank worked with Hank Mobley in Harlem for several years and studied under Charlie Persip. He worked with Sun Ra starting in 1964 and recorded several times with him. He worked extensively on the New York jazz scene in the 1960s and 1970s; he played with and was influenced by Ornette Coleman, and helped found a group called the Melodic Art-Tet in 1971 which was devoted to playing in Coleman's harmolodic style. This group also included Charles Brackeen, Ahmed Abdullah, William Parker, and Ronnie Boykins. Other associations included work with Bill Barron, Don Cherry, John Coltrane, Dennis Charles, Walt Dickerson, Kenny Dorham, Frank Foster, Charles Greenlee, John Hicks, Ken McIntyre, Pharoah Sanders, Archie Shepp, and Charles Tolliver. He relocated to Atlanta in the 1980s and led an ensemble there, but moved back to New York in the 1990s, where he lived in the Williamsburg neighborhood."
