There are certain things a man's friends don't want him doing around them, things he does while sitting pantsless in a darkened room, furtively searching the Internet for...a site where he can brag about all the sweet concerts he's been to! Your search is over, sicko: Songkick.
Just re-launching with a buttload o' new features, Kick alerts you when your favorite artists are in town, and now also lets you compile and share a face-melting history of past shows you've attended, because you didn't see Phish 479 times for the gooballs...you went for the respect. On the impending gig front, just pick bands you want Kick to track, and they'll crawl 29 ticket retailers to source upcoming shows, then email you when they're scheduled to rock your hood; you can also let Kick's "songkicker" app determine faves from your iTunes/Winamp/Windows Media Player library, helping you realize that even though you bought the Boomerang soundtrack for the P.M. Dawn, you wouldn't mind seeing Toni Braxton and Babyface live. The all-new meat's a "social concert database" housing info on over a million past shows (which appear when you search for artists), allowing users to create a personal gigography of stuff they've attended; click the "I Was There" button and the show'll be added to your list, where you can get next-level by entering the set list, uploading photos or vids, or posting a personal review, 'cause if you're vain enough to meticulously catalog and share your attendance record, you probably think that show was about you.
If any of your favorite past gigs aren't on the list, you can add 'em yourself by simply dropping deets on date, venue, headliner, and supporting acts -- cause the only thing cooler than bragging about the concerts you've been to is bragging about your awesomely deep knowledge of opening bands.
