LOLLAPALOOZA 2010 | In three short years, Lady Gaga has gone from a brunette side-stage skin show to festival headliner

Lady Gaga isn't known for subtlety or subdued performances, and when she headlines the first night of Lollapalooza 2010 next weekend, she'll no doubt deliver an earful and an eyeful.

Lollapalooza founder Perry Farrell already has admitted to spending up to $150,000 for the production of this single, two-hour performance. Lady Gaga's current Monster Ball tour features 15 over-the-top costume changes, plus a giant gyrosphere, a flaming piano, a neon car, a series of skits and an enormous squid attacking her onstage.
