I think I can go one better. As you probably know most of the bands reviewed on PUG offer their wares via Bandcamp. Here is a link to ALL the psych rock bands that reside there.
To listen to a sample track click on a cover and then click the cover bottom left to take you to the home page where you can stream (in most cases) the rest of the album. That should keep you busy for a week or two.
You can also check this link for artists who don't classify themselves as "rock bands" but still put out psych music in some genre.
NB You will have to copy and paste these links into a word doc and turn it into a hyperlink to reach the page. Pasting it into your browser wont get you there for some reason.
Cool thanks again, actually one of my pet hates is poorly designed websites with rubbish navigation even more irritating when it's supposed to be an upgraded or replacement site. This one I like.
