From Wikipedia on Mick Barr:
Mick Barr is an American avant-garde metal guitarist. Notable for his relentless speed and agility on his instrument. He has also released albums under the names Ocrilim and Octis, consisting of his own guitar over a drum machine. On the difference between the two, he says "Ocrilim is Mick Barr overthinking. Octis is Mick Barr underthinking. These names mean nothing when a live show is concerned. Come see Ocrilim and you may be forced to watch Octis."
As Octis, ten intense minutes LOCKED IN with a drum machine:
