Lauryn Hill wants to keep her music interesting.

The former Fugees singer changed the arrangements on some of her classic songs at her recent gigs because she wants to keep them fresh, but realises that her fans may not appreciate her efforts.

The 'Everything Is Everything' singer told MTV News: "I have to upgrade them a bit so that they're still exciting and fresh and they're new. There's something almost jazz-like in the way I approach performances. I'm not sure if the audience really understands. We need, or at least I need a certain amount of spontaneity, a certain amount of improvisation every show."

The singer - who had a successful solo career after leaving The Fugees - credited her former band with instilling a love of improvisation in her.

Lauryn said: "I might have gotten spoiled from the Fugees days. We used to improvise a lot. It kept it so fresh and exciting. I need that. I need that improvisational, almost jazz-like improvisational dynamic when I'm onstage. It keeps it so exciting.

The reclusive star - who has not made an album since 1998s 'The Miseducation Of Lauryn Hill' - also hinted that she is ready to return to recording.

She said: "This is an athletic discipline."You gotta be in shape to do it mentally, emotionally, spiritually, physically. But it's time. We're excited about what the future holds."
