Finally, a non-bootleg issue of one of Miles Davis' greatest electric performances ever [...] This night is auspicious because audiences - most of which were there to see the Steve Miller Band or Neil Young and Crazy Horse [...] responding with a confused, bewildered applause, with a couple of rowdies calling for an encore. It doesn't matter. The historical significance of this record is paramount. It is unedited and released as the gig happened on that day -- which makes it virtually unique from every other electric Davis live performance. This is music as exciting, revelatory, and dangerous today as it was on March 7, 1970. It's about that time.
