We'll start off with one of last year's top 100, #50 to be precise. UK powerpoppers Silver Sun with Dad's Weird Dream. This one's a must, so if you didn't pay the import price for it, now's a good chance to get it inexpensively.
The other two lean toward the more psychedelic side of power pop: Doleful Lions' Song Cyclops Number Two, and The Green Pajamas' The Night Races Into Anna. Grab these two and party like it's 1967.
