Guitar, bass guitar, midi keyboard, vocoder
I love mash ups! Check out Judgement night with Onyx and Biohazard that stuff is nuts!
By default I have to say Low End Theory by A tribe called quest. I must have purchased that at least 10 times in my life.
Right now I am learning Ableton trying to find my niche in there. I like to vary my instrumental styles a lot and then add some super bangin rap drums. Closest to it is probably B.O.B. how that album changes genres but stays hip hop.
