His short name is Tetsu. He is the leader for a japanese band called L'arc-en-Ciel.. Oddly enough the band's name is french and it means "Rainbow" Tetsu is an amazing Bass player maybe not as fast fingered as some well known english bass players (jaco) <-- I hear his name alot... But he is pretty good.. I personally love japanese music.. and him being the leader makes me like the band even more It's good to hear of Bass players as leaders for bands.. It makes alot of sense to us now that we understand the importance of the Bass, Alot of people even one's I know personally think the bass guitar to be a simple instrument and that the Electric is alot harder.. But we know better ha,ha,ha!
