Suggest one obsure album we all should hear

Zappa Apostrophe, Wishbone Ash first 4 albums, Skin Alley Two Quid Dead, Patto Patto, Colosseum Live, Captain Beefheart Trout Mask Replica, East of Eden Mercator Projected, Snafu, Eric Burdon Declared War

A great reference track for checking out amps/speakers is “Flight of the Cosmic Hippo” on the album of the same name by Bela Fleck and the Flecktones.

Not only is this a great track to put a speaker through some paces, the group is quite good to hang with a beer of glass of wine, being a blue-grass fusion band.

Sandstone,

I agree that Harry Partch is extraordinarily underappreciated.  I love his "Delusions of the Fury."

This thread is clearly far advanced and there are many of both albums I love and music I don't know but here are a few that I haven't seen that always hit me where I live.1) the oldest maybe- Running, Jumping, Standing Still by Spider John Koerner and Willie Murphy.2) Journey To The End Of The Night by the Mekons3) The Graceless Age by John Murry a descendent of William Faulkner's4) the 2nd Soft Machine album -the band was mentioned before I think but their first two albums are unlike their later stuff with Robert Wyatt  drumming and singing before he broke his back and became paraplegic.5) From Sweden With Love by the Art Farmer Quintet, when Art was playing with Jim Hall it was music to melt by as was Undercurrent when Jim was duo with Bill Evans and any of the Paul Desmond albums with Jim Hall.By the way there was a little confusion above as there was the American band BoDeans and there was a maybe better band in the U.K., the Bodines.I never saw the Velvet Underground (I grew up in Southern California) but in 1967 my best friend as a freshman at Pomona College started playing the Velvet Underground with Nico which we listened to endlessly.Lastly 3 quick others6) Tim Buckley - Happy Sad (I know he is not obscure but this was stunning to me and I was already a fan7) Town And Country by Humble Pie - not like the bombastic Pie that most people heard but really showing Steve Marriot could sing8) One For The Road by Ronnie Lane's Slim ChanceGolly I could go on and on

oldbear,
+1 for "Running, Jumping, Standing Still by Spider John Koerner and Willie Murphy". Interesting album indeed!
