Replying to gigging

so me and my band played our first gig last night. we played a small cafe in hartford, connecticut. it was hot shit. there were a bunch of bands playing and we were the first. a little through our set, our friend john came up and sung, then flowed with us. the crowd dug it. when the second band started, everyone stopped paying attention and walking in and out and talking. we even got another gig at a university nearby, from a guy who was there. what's the best way to go about getting a lot of shows?
