My all-time favorite live performer is Stevie Wonder. It would be great if Wolfgang's Vault had other Stevie Wonder shows, since his only official live release (Natural Wonder from 1995) is good, but does not represent his 1970s-1980s peak. My second favorite live act is Derek & the Dominos - it would be great if you had additional D&D shows, too.
This site is amazing. Some of the shows are complete revelations, such as: Todd Rundgren '78, Fleetwood Mac '74, Traffic '73, the Tubes '74, Van Morrison '78, JOan Armatrading '77 etc.
Thanks to everyone at Wolfgang's Vault for this wonderful site!
