The wall is a fairly miserable album, but, its a long long long way fomr their best. Check out Echoes, it is a superb album, probably their best. Dark Side of the Moon, what most people say is their best. If you want really weird, then listen to their 'Piper at the Gates of Dawn' album (bits of it are on youtube), their first album which is probably their best. Its why Waters left the group. Everyone got pissed of with his miserable childhood songs. The early stuff was all Barrat Gilmour and Wright.
