David Crosby - guitar, vocals
Phil Lesh - bass
Bill Kreutzmann (?) - drums
Jerry Garcia - guitar, vocals

Notes:
- New source to circulation.
- There's debate as to when the three night run at the Matrix occurred, and which night this recording is from.
- Mickey Hart is often credited on drums, but Bill Kreutzmann was on drums with the same ensemble days later at Pepperland.
- There is no digital noise reduction on this source.
- Early parts of the public performance have some tape-related print through, most noticeable in 'Deep Elem Blues' and 'Drop Down Mama'.
- Splice in 'Motherless Children' at 3:20.
- 'Bertha' makes a public appearance about two months before its first live performance by the Grateful Dead.
