Performer: Rex Stewart

The unassumingly-titled "That's Rhythm" is a colorful tune that straddles the line between the swing era and the bebop era. Written by Ellington sideman Rex Stewart for his own shorter-lived 4-horn band, "Rhythm" features a punchy and memorable head and lots of solo space.

Back Room Romp is basically a simple blues in Ab, but there is a twist: the head is a series of building independent lines, thus a "Contrapuntal Stomp." Every horn player gets a solo chorus. The lead trumpet part is a bit of a blow, but this was written for longtime Ellington sideman, trumpeter Rex Stewart, who had the chops to play all day.
