Here's a sample from another obscure Arthur Custer album I picked up. The piece, Rhaposdality Brown!, was written in 1968 according to the notes.
The sample above was written in 1958 (from the back cover): for an ensemble consisting of 2 Trumpets, 2 Horns, Tenor Trombone and Bass Trombone. There are three movements: Allegretto, Adagio and Presto, which in performance turn out to be Brisk, with alternating clusters and contrapuntal passages; Slow, mysterious, chorale-sounding, evocative; and Brightly, lively and bouncy as a jig with a fine, driving finish.
