You can do it!
And yeah, The Piper At The Gates of Dawn is on my list of "albums you must listen to while on LSD". In fact, its at the top of the list. Talk about defining what "Psychedelic Rock" means. What's interesting is Piper and Sgt. Pepper's Lonely Hearts Club Band were both recorded at the same studios at the same time, and both bands (Pink Floyd and The Beatles) routinely sat in on each other's recording sessions. You can bet lots of LSD was involved. Sgt. Pepper's is the second album on that list, by the way.
