Query: Excellent time capsule

this is an approx. 1-hour color videotape, 16-track recorded snapshot of February 1970 performances by these three bands at The Family Dog in San Francisco. Originally produced at the time for public television broadcast; see the review entitled "Amazing Performances" for details ... also disagree w/ "It's Not the 60's" review comment: Grateful Dead were still to break new musical ground from 1970-74 esp. after 1971 when Keith Godchaux joined on piano, as was Santana with even more jazz-oriented 1972-74 albums and lineups (powerhouse drumming from Michael Shrieve here).for 58 minutes you'll be transported to a time and place in music which can't come back - savor it.
