This is strictly 60s and 70s BTW
I would say that any true prog fan should have at least one album from at least ten of the following bands, which I consider to be the main players. Feel free to add and take away, but I can't see how any of these bands would be taken away. Most of these bands continued for more than a decade and is part of the reason why some appear in the list.
Genesis, Yes, Pink Floyd, Camel, Van Der Graaf Generator, Focus, Ash Ra tempel, ELP, Gentle Giant, Caravan, Jethro Tull, Eloy, Gong, Hawkwind, King Crimson, The Moody Blues, The Soft Machine, Steve Hillage, Mike Oldfield, Can, Nektar, Barclay James Harvest and Jade Warrior.
I have many cds by all of those bands above and although I d/l from hundreds more, I need to be pointed in a good direction when it comes to 2nd-tier bands and purchasing actual cds.
