Piper At The Gates Of Dawn
 

Holy shit this album is incredible. I think this is the best album Pink Floyd has ever made. The rythmn is extremely catchy in most tunes (Lucifer Sam) and it's got that trippy, Pink Floyd feel. I'd say, in order their best three are

1. Piper
2. Animals
3. The Wall

I still think DSotM was the best. :(

IF you like Piper, you'll shit your pants when you dload the mono version. Interstellar overdrive has a whole new keyboard track, and the drums are amped up. Unfortunatley, it doesn't have the coda with the speaker swishing.
