It appears that Ween have officially called it quits. Speaking to Rolling Stone, Aaron Freeman -- aka Gene Ween -- said he's retiring his alter ego because "it's time to move on."

The news comes after Freeman released his first solo album, Marvelous Clouds, just a few weeks ago. Last year, he checked into rehab for substance-abuse issues after several erratic performances, but says he's on good terms with the band's co-founder, Mickey Melchiondo (Dean Ween).

"For me it's a closed book. In life sometimes, in the universe, you have to close some doors to have others open," Freeman said. "There's no, 'Goddamn that such and such!' For me, I'd like to think it's a door I can close finally."

Started in 1984 when Freeman and Melchiondo were in eighth grade, the band made its mark with an eclectic, experimental sound. Ween had a surprise hit with their first major-label album, 1992's Pure Guava, and its single "Push th' Little Daisies." The band's last full-length was 2007's La Cucaracha.

After Marvelous Clouds, a covers collection of songs by Rod McKuen, Freeman plans to work on a record of all original material. "It's important to know that this isn't a side project. I'm forging a new thing for myself. So that's all. There's no plans for any records or touring for Ween from my end."
