I didn't need to buy the albums I just got the songs. Chicken Huntin, Cotton Candy and Popsicles, Homies, Southwest Voodoo, Blaaaam!, and Under the Moon (which actually made me cry) just to name a few.
I used to date a guy that was into the ICP and TWZTD but ...I have never seen them before and I only heard them when I was dating him...it was a short lived relationship...I think they are interesting folks though. I hope you had fun at the concert
