I find most of these obscure psych albums on RYM these days. Also subscribe to a few Youtube channels that feature rare (mostly psych) albums in their entireties but I don't check those out since I left me former job (where I was on the phone less often than I am at my current position).
Never the Evans but I've been checking out more and more of his stuff lately. Learning more and more that live albums are really the way to go with him. His "Montreaux Festival" and "Town Hall" albums are damn good and from what I've heard, "The Paris Concert" has some of his loveliest playing.
Yeah kinda strange you never checked out Television considering "Marquee Moon" had the #1 album spot. Obviously ins't *that* good but worth checking out (and I tend to stay away from most things with even slight odors of punk). Think most would agree that this song is their best (10 minutes might seem long for this type of thing but a lot of cool things happen):
