Rocker Billy Corgan has hinted The Smashing Pumpkins' days may be numbered after revealing the group's next album will be its last.

The band is slated to release Day For Night next year (15), but Corgan has not made it clear whether that album or its follow-up will be the band's finale.

He tells the Wall Street Journal, "The next album is like the end, end, end. The trite way to say it is I'm over rock 'n' roll, which is strange because rock 'n' roll is getting back into me. For a lot of years, I cared too much and wrestled with what it meant to carry on a legacy. My legacy was greater in my mind than what other people were giving me credit for.

"When I started to go off it, people started to say, 'Oh, by the way, you were really good. Can you start playing that s**t again?'"

Corgan also feels his fan base has diminished and people listening to his music now do not appreciate it as much as his past fans did.

He continues, "I would define a fan as someone who explores the depth of the artist's work, and allows the artist to show you something. It's not up to the artist to walk you by the hand. I don't think there are that many of those people who exist. I'd say they're in the low thousands."

He adds, "This is where I start to complain, but I think the depth of my work and the depth of my catalogue is just now beginning to be explored in the way it was intended to. For whatever reason... I have not gotten the cultural review worthy of my position."
