Thanks for registering and adding your list -- I'm kind of jealous that you've seen David Gilmour!
Since we just launched 24 hours ago, it is currently a personal journal that you can organize and share with friends on Facebook and Twitter.
The vision is social and discoverability. We will enable you to follow other users that like similar bands to you, and see everyone that has been to the same shows as you. This will help you discover new bands and find shows in your geo area.
