The modern jazz revolution which came to be known as bebop was distinguished by a level of melodic-harmonic complexity and rhythmic brinkmanship which required the most elevated levels of instrumental virtuosity imaginable. As if to drive the point home, composers such as trumpeter Dizzy Gillespie crafted certain tunes to function as musical obstacle courses, which quickly separated the men from boys--without mercy. Such is the premise on For Musicians Only, save that with a driving rhythm section keyed by bassist supreme Ray Brown, and saxophone masters Stan Getz and Sonny Stitt on board as the other horns, there is no shortage of musical fiber. Brisk tempos and challenging chord changes are the order of the day, with Gillespie's anthemic "Bebop" setting a daunting standard. The trumpeter is in peak form here and on a riveting "Lover Come Back to Me," articulating breathtaking runs and high-wire rhythmic variations with all the fluidity of a saxophone, but with a tart, crackling tone all his own. Stitt, as is wont, plays with incredible speed and rhythmic articulation, and anyone who visualizes Getz as no more than the arbiter of cool tenor, should take note of this sheep in wolf's clothing's relentless melodic intensity on "Wee (Allen's Alley)." --Chip Stern
