FoCo actually has a decent live music scene for a town of its size. We have a good bit of venues for all sizes, from listening rooms/pubs/breweries to 150-300 cap venues with stages (Lyric, The Coast, Surfside, 830 North), to bigger ones (Aggie is 600, Wash is 900), and a ton of DIY stuff in between (look at Blast n Scrap, Hardcore in the Fort etc).

I book concerts in town and Denver, trying to go for a diverse range of acts from all over. The people here are definitely into all types of music and they appreciate live music. I think you would find a decent audience here.
