The 55th Annual Grammy Awards aren't until Sunday but the music industry has decided to get a head start on the festivities. There are award ceremonies leading up to the awards (go figure), pre-parties, concerts, and gifting suites happening across L.A. from now all the way through to the after parties following the show. Grammy Week tends to be the most fun of the awards season lot because if anyone knows how to throwdown, it is the music industry. It would be a shame to miss out on what might be L.A.'s biggest open bar week of all, so we present to you our 2013 Grammy Week Party Guide with all the top events going down. Navigate your party path wisely and enjoy the musical takeover while it lasts.
