Last week in Chicago, [artist id="3061469"]Lady Gaga[/artist] felt the power of [article id="1645327"]Lollapalooza[/article] overtake her when she jumped onstage with her pals the Semi Precious Weapons and decided [article id="1645318"]to crowd-surf[/article].

It was a moment her "little monsters" eagerly welcomed. On Wednesday (August 11), she called in to Ryan Seacrest's radio show and explained that she hadn't planned it; she just really wanted to crowd-surf.

"I was so excited 'cause I haven't crowd-surfed in a long time 'cause no one lets me anymore," Gaga said. "It was great," she continued. "I love Semi Precious so much and they're my band ... I don't know what came over me. I just got so excited and I remember playing that stage and what it felt like and they were doing such a great job. ... I just jumped."

The Semi Precious performance isn't all that's gotten Gaga all jumpy lately. The recent overturning in [article id="1645116"]California of Prop 8[/article] banning same-sex marriage was also inspiring to her.

"I felt like it was a revolution, a gunshot went off. It was so exciting when it happened. For me, it was a moment that indicates it can happen in every state now," she said. Gaga was so excited by the ruling that she decided to pen more music.

"I was so happy, and I went right into the studio and I kept writing," she said. "[My album] kind of is done, but I can't stop writing music. I don't know what I'm going to do. I might have to put out two records."

Gaga didn't spill too many beans about the

[article id="1641989"]next album[/article] but noted that she already had a thesis of sorts for it.

"I never stop writing, so even when my album's done, I'm always working," she explained. "When I put this album together, I wanted to write the album in an innovative way. I want the message to be innovative. I already have the sonic ideas and the message ideas. ... I basically asked friends of mine to produce the record with me, and we're called the banditos."
