Oh the joys of listening to Pink Floyd under influence for the first time! Another good album although it definitely sounds different to TDSoM is Wish you were here. The album was heavily influenced by mental deterioration of a former band's leader Syd Barret, so it has quite an emotional undertone in its flow. http://www.youtube.com/watch?v=R0sw2CgysWY and http://www.youtube.com/watch?v=9qEsTCTuajE both are amazing songs and I hope you will enjoy them!
