I really want to like the website Bandsintown.com though living in a larger city seems to be a requirement. If I still lived in San Francisco, I could opt-out of all the emails I was receiving from the local venues and just visit Bandsintown.com to get informed on the upcoming shows.
Bandsintown.com uses your location and Last.fm record to display weighted links, similar to a category or tag cloud, for all bands playing in your area. You can adjust the date range, price, and distance to change the results. The site relies on user input to expand the venue details and write reviews, placing Bandsintown.com somewhere between Yelp and Last.fm.
The Events page on Last.fm offers a similar feature without the fancy options to adjust your range and prices, and Bandsintown.com relies on Last.fm to recommend shows in your area. You can't have Bandsintown.com with Last.fm, but you can use Last.fm Events without the need for other tools. Bandsintown.com has potential until Last.fm - which is already established - adds more options to their Events page.
