Fellow singer-songwriters Aimee Mann [ tickets ] and Duncan Sheik [ tickets ], both of whom are spotlighting material from new albums that they released last August, have assembled a three-week tour of U.S. clubs.

Mann's new album, "Lost In Space," marks her second consecutive self-released LP. Among the artists who contributed to the disc were husband Michael Penn, producer-musician John Brion and signer-songwriter Jason Falkner.

Mann formed her own label, Superego Records, after various record company shake-ups in recent years left her shuffling from one label to the next. Her first self-released album, 2000's "Bachelor No. 2, met with critical acclaim, and was buoyed by similar accolades for her work on the previous year's "Magnolia" soundtrack, which included her Oscar-nominated song "Save Me."

Even without major label support, "Lost in Space" managed to enter the Billboard 200 chart at No. 35.

Mann gained fame in the '80s during her stint as lead singer of 'Til Tuesday, a group best known for its hit "Voices Carry."

Sheik's latest album, which was produced by Patrick Leonard (Madonna, Jewel), is titled "Daylight." The London Session Orchestra appears on four of the album's tracks.

The New Jersey-born, New York-based Sheik is best known for his hits "Barely Breathing" and "She Runs Away."
