hey bro..
speaking from personal experiences,
well actually MOST studios allow a 'drums only'session..its just that u have to ask them.
i used to practice at jamming studios(fourtones,club paradise,beat merchants,velvet joint etc..)i told them that i'll be only playing the drums and they allowed me to at a price different from jammin rates,like say 10bucks an hour.yea so go out there and explore.haven tried the one at drum resources though..i think its like 22bucks an hour.heehee but the kit over there is like WOW!
many different variety of tom toms and cymbals..worth the money,ahahha.
so ya call up some studios and ask them.
