I grew up with VDGG. IMO their best album by far is Pawn Hearts, all others take a lot more effort to dive into. After that check out Peter Hammill going solo, his best albums are Nadir's big chance, Patience and Enter K. Enjoy!
I just discovered Van Der Graff Generator...
An interesting experimental British band from the 60s and 70s. Their music is interesting, however they're not for everyone. Please give them a try and let me know what you think.
Thanks.
PS... you need an open mind for this band.
