The Mahavishnu Sounds

Talk about "elusive discs":

1972 Japanese-only promotional 7-track LP that was never commercially released, focusing on the band members' pre-Mahavishnu releases including John McLaughlin with Miles Davis & Solo plus Jerry Goodman with The Flock & Billy Cobham with Dreams. The textured sleeve is a unique design featuring incredible artwork by Taul Satoh with track/artist biography, selected album details on the back in Japanese & the tracklist in English.
