And Christopher saves the day once again -- exactly what I was looking for, thank you!

To the rest of you, thank you for the suggestions. I'm, of course, familiar with all of those artists and I definitely know what the psychedelic sound is (hence why I want to use it). I was specifically looking for some quick shorthands and techniques in terms of chord progressions to get there in eight bars. It's difficult to sort through chord charts and pick out what's native to the style and what's not. Christopher's advice gets me there, I think.
