Ask HN: What is the concert calendar that sucks least?

Songkick offers a great solution for concert tracking. I use it all the time. It allows personalised tracking of artists that you like and much more.

Reverbnation is one of the most comprehensive in my area for indie bands, but it lacks a few key venues. Last.fm has quite a few concerts listed, but usually only bigger name acts. Indie zines and weekly newspapers seem to be the best offline source.

Seatgeek, especially their Columbus discovery engine. http://seatgeek.com/columbus

I use Tourfilter. Big popular and small local acts are posted by individuals who follow the bands.
