Bob Katsionis is the keyboard player for the Greek power metal band Firewind. Bob cites Kevin Moore, Jens Johansson and Keith Emerson as his main keyboard influences. As well as playing keyboards, Bob is also a seven string guitar player and has played both instruments in his various bands - when Firewind play live he performs in a dual role as keyboard player or rhythm guitarist (or both), depending on the individual song. He uses a standard six string guitar in these circumstances. Bob also has an instrumental solo project - so far three albums have been released.
