LaoTzu

Please help.

I need to expand my playlist which hasn't changed much in the past six months or so. Here it is in it's entirety:

Tool - Opiate, Undertow, Aenema, Salival, Lateralus
APC - Mer de Noms, Thirteenth Step, eMOTIVe, and you guessed it... aMOTION the DVD

Who can I add to this list? I know there are artists out there worthy of standing in Maynard's company. Please help...
