Without a new album to promote during his upcoming summer tour, vocalist Clay Aiken [ tickets ] will instead dot his performances with his renditions of songs from all five decades of the rock era.

"I thought it would be cool to sing a bunch of covers, and relate to everybody," Aiken said in a press release. "There will be songs my mom likes and my grandparents like, and there are a lot of people who love the music of the '70s. I like the '80s, and we're going to have a lot of fun with songs from the '90s."

Aiken's setlists will feature many songs that he's performed in the past, including Simon & Garfunkel's "Bridge Over Troubled Water" and Neil Sedaka's "Solitaire"; he'll also do a medley of Elvis Presley songs. Songs made popular by Sam Cooke and the Goo Goo Dolls will also get the Aiken treatment, according to RCA Records.

Aiken's hits--as well as some material he plans to record soon for a new album--will be highlighted during the '00s section of the shows.

The summer tour launches July 28 in New Jersey, and runs for more than a month.

The outing is Aiken's first since a late-2004 holiday run that backed his most recent release, last November's "Merry Christmas with Love." That set followed his 2003 solo debut, "Measure of a Man," which entered The Billboard 200 album chart at No. 1 and spawned 2003's top-selling single, "This Is the Night," as well as the hit "The Way."
