Well if you're a huge Veedon Fleece fan I'm probably not going to be able to suggest much that you don't know, because that album is among the lesser-known and appreciated Van albums. I think of it as of a piece with Hard Nose the Highway (released the prior year), so if you don't know that, get it. Title track alone is worth it, with one of my favorite Van opening lines ever:
Hey kids dig the first takes
Ain't that some inspiration
When Sinatra sings against Nelson Riddle strings
Then takes a vacation
I'm mostly an album guy when it comes to Van, and No Guru, No Method, No Teacher is probably my favorite of his lesser-known albums. "In the Garden," from which the album title is drawn, is among my favorite Van tunes of all time, but the whole album is a great listen. Poetic Champions Compose, from that same vintage, is another gem of an album imo, including "Alan Watts Blues," which I listed upthread, and also 'Queen of the Slipstream," "Someone Like You," "Give Me My Rapture" and his unofficial theme song, "Did Ye Get Healed?," to which he frequently enters or exits his sets.
And Into the Music is one that I am always shocked more people don't know. Chock full of great, great songs with good energy.
I own literally every album except the one that was just released this week (I've sampled it and am still on the fence because I'm not crazy about what I've heard--not big on the crooner cover stuff from either him or Dylan, two of my top five all-time artists). I enjoy listening to every single one of them.
ETA: Also check out "Listen to the Lion," "Who Drove the Red Sports Car," "T.B. Sheets," "John Henry" and the live version of "See Me Through/Soldier of Fortune/Thank You Falentinme Be Mice Elf Again" off A Night in San Fransisco.
