SiliconBeat blogs about Podbop, a site that combines podcasting and local. It allows you to hear podcasts of bands that are playing in the local market. One can search by artist or location. The site links to Eventful.com, which provides the venue information.
Local events are a relatively still undeveloped area online — probably a feature or RSS-based feed rather than a stand-alone application or destination in my view. Along those lines Yahoo! not long ago acquired Upcoming.org. And IAC’s Evite has pushed into local events as well.
Jambase is another local music events and community site.
