1978 studio album by Pete Christlieb and Warne Marsh
The Rolling Stone Jazz Record Guide states that "Apogee is an unadulterated burner, guaranteed to work for tenor freaks."
The AllMusic review noted: "Apogee is an anomaly in many ways. First, it is a Southern California answer to the great titan tenor battle records of the '40s and '50s. Rather than sounding like a cutting contest, it sounds like a gorgeous exercise in swinging harmony and melodic improvisation by two compadres. ... the pair engaged a kind of freewheeling, good-time set that remains one of the most harmonically sophisticated recordings to come out of the 1970s." On All About Jazz, Chris M. Slawecki observed: "It is impossible to distinguish one man’s tenor from the other: sometimes they swing in unison, sometimes harmonizing, sometimes in duet or counterpunching, but they are always strong, meaty and powerful." In Jazz Review, Mark Keresman called it "a sterling set of beautifully recorded, searing, straight-ahead, mainstream bop tenor madness."
