With the departure of Syd Barrett, Pink Floyd has a lot of trouble establishing what it was going to be. Barrett, their principle song-writer and god-head, having succumbed to one last acid freak-out, left PF rudderless and without any musical direction. Good. Lots of experimentation later, PF found their direction, a series of albums later, PF released 'Meddle', a brilliant creation that forever removed PF from Barrett and prepared them for the success they would unleash with 'Dark Side of the Moon'. There is not a single bad track on this album. But climaxing with 'Echoes', as stellar as space-rock will ever get, PF takes the listener into new and higher realms of sonic delight that few, save for The Who, have been able to accomplish. Must have.
