you've prolly been to more hip-hop shows than all of us but

i thought a good set was like 45mins-1hr. i guess it depends on who you're touring with. if there's a lot of people on the bill, as you mentioned about Smoking Grooves, then the time will be shorter. but if you perform by yourself with maybe 1 opening act...you better do at least 1 hr/ hr and a half cuz the people wanna get their money's worth.
