As with the original Mahavishnu recordings of the '70s, the music on Live Bootleg is extraordinarily complicated and jam-oriented, suggesting why the Mahavishnu Orchestra is cited as an influence on everybody from King Crimson to Phish. The two-disc set, which the Project has been pushing since spring, is 120 minutes of powerful fusion. These musicians are not only ambitious; they're good enough to have been blessed by McLaughlin himself. At 60, McLaughlin is engaged in Shakti, his jazz-raga fusion vehicle. Meanwhile, Mahavishnu's inspiration lives on in a band that twines "The Dance of Maya" and "Birds of Fire" with Mahavishnu-spawned originals, attesting to the improvisatory spirit that fueled fusion in the first place.
