Bassist and composer was one of the founding members of . He left after 1973's , disgruntled over a change in direction toward funk. However, as evidenced by 2009's , an homage based on themes and ideas, his respect for the music never diminished. On , and his sextet offer exploratory variations of compositions he recorded them during his tenure with , and key tunes created after his departure. Drummer and saxophonist return from the 2009 session, but recruits seconds at each instrument -- saxophonist and drummer -- and adds the massive keyboard talent of . ' signature upright bass is often played arco with a wah-wah pedal, and he adds additional keyboards. There are two "Scarlet Woman Variations" with slightly different titles. uses 's melody, but extrapolates the harmonics, opening them wide to expose a bluesy balladry underneath, articulated by a haunting synth, and saxes in sparse call and response. His woody plectrum upright and arco playing flit amid ghostly rhythm traces and ambient electronics. "Birdland Variations" uses its memorable melodic theme, breaks it down to its essences, and rebuilds it radically without losing the hook. Its notion of time is stretched, with one drummer playing 3/4 while the other swings in 4/4, leaving the saxes free to decide whom to follow. His wah-wah expressionism bridges all four players and he delves into funk as 's keys illuminate the interior and color the margins. uses familiar themes in his own three "Multi Dimension Blues" interludes that bind these tunes together. The reading of 's "Pinocchio" (first recorded on ' in 1967, then in 1978 on 's ), juxtaposes ' effects-laden arco playing along with a soprano and tenor sax engagement that relays the primary melody in elemental statements. reconstructs the harmony using fragmentary notions in striking progressions.

This version is closer to the latter, offering a forceful exchange between drummers and head-to-head conversation from the saxophonists. and crack open color and textural palettes from the inside, illuminating both poles. "Morning Lake" is darker than its 1971 original, as ambient synth swirls, shimmering Rhodes, and skittering alternate drum patterns create its elusive spine. Intermittent interplay between horns offers modal melodic fragments. The bassist's wah-wah pedal is the pulse. The piece floats, simmers, and eventually explodes with the sample of a thunderstorm to close. While 's rock and funk fans may require a couple of listens to find the grooves, they are certainly there. Jazz fans should readily embrace as top-flight 21st century fusion, rife with canny improvisation by an excellent group with an inspired leader. ~ Thom Jurek
