Singer K.D. Lang, who last summer toured the U.S. with her recent recording partner Tony Bennett, heads out alone this time around.

Lang so far has scheduled about a month's-worth of dates that begin at the Newport Jazz Festival in Rhode Island on August 8. The singer also has a lone June performance planned in Philadelphia.

Lang's most-recent release is last November's "A Wonderful World," on which she and Bennett duet on a collection of songs popularized by Louis Armstrong.

T Bone Burnett, who picked up the 2001 Album of the Year GRAMMY® award for the "O Brother, Where Art Thou?" soundtrack, produced the set. It was recorded in a series of marathon sessions over three days at the Harms Theater in Englewood, N.J., using all live instruments.

According to the album notes, the theater--which was once the site of vaudeville shows--was emptied out for the sessions except for the two singers, the producer and a 50-piece orchestra.

On Monday night (4/7), Lang and Bennet are due to perform together at the 14th annual GLAAD (Gay & Lesbian Alliance Against Defamation) Awards in New York City, according to Lang's website.

Some time this summer, MCA Nashville plans to release a tribute album titled "Remembering Patsy Cline," which will feature Lang's version of Cline's "Leavin' on Your Mind," according to the label.

"Invincible Summer," Lang's most-recent collection of new studio material, surfaced in 2000. She followed that album with 2001's "Live by Request."
