Lollapalooza has posted a teaser lineup for the upcoming festival, giving us only the “O” letters. If you remember back in February we broke the news that Lady Gaga, Green Day, and Soundgarden are to headline the festival. We invite you to try and fit those names into the first three spaces.

Tickets are on sale here.

Here are our confirmations from the top line:

Arcade Fire, The Strokes, Phoenix
