THE MAIN ONE O’Clock Lab Music group, a big jazz ensemble with five saxes, five trumpets, five trombones, guitar, piano, bass, drums, percussion, and occasional vocals, isn’t a static ensemble at all. THE MAIN ONE O’Time clock group may be the premier degree of nine rings that function dynamically from the Jazz Research Division on the School of North Tx University of Music. The name originates from enough time the group rehearses — from 1:00 p.m. to at least one 1:50 p.m. four times weekly (gleam Two O’Time clock Lab Music group) — and playing areas in the music group are highly valued. One edition or another of the Lab rings continues to be playing concerts because the early ’40s and documenting since 1967 with a number of different directors, and a large number of LPs and CDs have already been released almost yearly ever since, a lot of that have garnered honours and high essential praise.
