Following to see what people have to say about this. Distant Sky and Live from KCRW are both good, but both are EP-length and certainly not a definitive 'live album' listening experience. I've never looked further back than that for live stuff.

For both of you, Live Seeds is a phenomenal live album. No vinyl unfortunately but at least give it a stream or CD listen. The opening Mercy Seat into Deanna is grade A live music and sets the tone for a perfect set.
