otherwise:
manDrum started out of a desire to play drums, coupled with a lazy man's ingenuity for taking shortcuts. Thus, the manDrum was born. manDrum is chris mandra (who also plays in psychedelic , electro-acoustic, world dance music band TELESMA ) who with friendly help from time to time (Sean Finn, members of Telesma) performs live, improvised electronic music using the manDrum, his laptop, his voice and a P5 VR glove. All of the music and sound is produced as it is heard; loops are created on the fly from playing or singing. It is, in the words of those who've seen it, "pretty cool".
ALSO, if you're at a show, afterwards mandra will talk to you and let you try his stuff.
One more thing: manDrum is really KatastatiK
