1) grooving with the band as a whole, giving a central beat and occasionally a driving force to the song. depending on the band line-up, i do prefer to leave basslines and give a driving melody/harmony to further support the band,
2) John Myung (his patterns, the way he follows portnoy's groove or j.petrucci's guitar or locks with rudess, and his sheer SPEED), Stu Hamm (his playing seems to suit joesatr's better than other bassists who have played with joe, and Stu simply has a wonderful tone on his bass, PLUS his playing style is amazing e.g. in "moonlight sonata 2-hand bass tapping" at a joe-sat gig, u can see him using his pinky to tap straight downwards and it looks like no sweat to him. he does seem to have some Victor Wooten influences! :lol: ), Billy Sheehan (for his out of the blue riffs that give punch).
