I just started collecting vinyl about a month ago, but here is what I have so far:
Traffic - On the Road
Moody Blues - Caught Live +5
London Chuck Berry Sessions
Chuck Mangione - Live at Hollywood Bowl
Eric Clapton - Just One Night
Eagles - Live
The Band - Rock of Ages
The Outlaws - Bring it Back alive
Ten Years After - Recorded Live
Hotels, Motels and Road shows (compilation)
Donovan - In Concert
Johnny Cash - At San Quentin
Cheap Trick - At Budokan
50+ Dead bootleg cassettes
There are quite a few I really want though, many on the lists above. Especially Allman Brothers and Frampton Comes Alive. Just waiting to come across really clean copies.
