It is surprising that the music on this double LP has not been reissued yet on CD for there are many exciting performances. Taken from Dick Gibson's 1971 Colorado Jazz Party, there are mini-sets from four separate groups. Trumpeters Clark Terry and Harry "Sweets" Edison lead a six-horn nonet (which includes Zoot Sims' tenor) for spirited versions of "On the Trail" and "The Hymn." Terry gets a chance to stretch out with tenor-saxophonist Flip Phillips in a quintet while a similar-sized group showcases the underrated trombonist Carl Fontana and James Moody on tenor. Finally there is a four-trombone septet (with Fontana, Kai Winding, Urbie Green and an effective Trummy Young) performing long versions of "Undecided" and "Lover, Come Back to Me." Fans of straightahead jazz who run across this two-fer will not need to be told twice to get it.
