The Byrds went through a series of incarnations and I love most of them. They started off nicking the Searchers jangly Folkrock and doing a Rock job on Dylan songs. They were great and Dylan liked them too! They went on to develop this psychedelic sound with 8 Miles High and 5th Dimension. Then they became very West Coast Acid Rock with Notorious Byrd Brothers (my favourite album). After that they went downhill. Gram Parsons took them down the wrong route with Sweetheart of the Rodeo with smatterings of Christian guff.
Never mind – we have a lot of their good stuff to listen to!
