The NYC CMJ Music and Film Festival (going 30+ years) is a week long industry showcase of developing musicians and film artists from all genres.
This year's will be held from October 19 to 23, 2010. I love that this is open to any artists who wants to showcase their talent. They just need to submit an application (and be good, I assume). So who knows what ya gonna get at the Festival! Right now they are selling tickets for the whole sha-bang. Basically, an all access pass to all the shows. Or you can buy single concert tickets. Most of these concerts will be held downtown Manhattan/Brooklyn. And you can get about 4 different acts in a concert. I haven't attended any of the films but I'll look into it this year. Check out the site (when it's more informative in a few weeks) if you're interested in something new.
