Well, I've come to this thread pretty late, but I'd like to add a few comments.
I first discovered Lloyd back in the 1960's on Chico Hamilton's "Drumfusion". Although his playing was Trane-inspired, I liked his passion and his compositional skills. Perhaps my favorite Hamilton with Lloyd is "Man From Two Worlds" (Impulse), featuring the original (and superior) version of "Forest Flower". "Passin' Through" (Impulse) and "A Different Journey" (Reprise) are also very good. Someone close to the Paul Butterfield Band once told me (and you can hear it) that "Passin' Through" was one of the inspirations for "East-West".
I saw Lloyd several times back in the mid 1960's in Boston and New York, just after he had left Cannonball and was putting together his quartet with Keith Jarrett. At the time he was signed to Columbia, and had released two excellent LP's, "Discovery" and "Of Course, Of Course", which featured Ron Carter and Tony Williams, who had worked with Lloyd whenever Miles was off.
I felt that with "Forest Flower" his playing became, to these ears, diluted, as if his flute playing had influenced his tenor, and not for the better. His popularity soared in the late 60's, as much for the "beads & bell bottoms" image as for the music, which was rather ordinary, I felt. The last time I saw him was around 1972, playing maracas on stage with the Beach Boys. Some of you may already know that he plays on two Beach Boys tracks, "Trancendental Meditation" and "Feel Flows". The Boys, in turn, appear on his albums "Waves" and "Warm Waters".
I have liked, but have not been blown away by, his recent stuff on ECM. It does seem more focused that the late 60's playing.
