Town Hall Concert is a 1964 live album by jazz bassist and composer Charles Mingus. It was recorded in New York City on 4 April 1964. "So Long Eric" is a 12-bar blues that got its name after Eric Dolphy informed Mingus he would be leaving the band to stay in Europe before a concert in Oslo. "Praying With Eric" is more commonly known as "Meditations On Integration". The album was originally released on Mingus' own Jazz Workshop label and subsequently rereleased on Fantasy as part of their Original Jazz Classics series.
