Paul McCartney returns to the one-man-band approach that marked his 1970 self-titled solo debut on "Chaos and Creation in the Back Yard," his 20th solo album since the dissolution of the Beatles. Due Sept. 13 via Capitol, the 13-track set was produced by Nigel Godrich (Radiohead, Beck) and is the artist's first new studio album since 2001's "Driving Rain."

"I did not want to rush this album," says McCartney, who played everything from guitar, bass and drums to flugelhorn and harmonium on the project. "I think it was worth the wait though. The music became more interesting over time and I'm really proud of what we did."

The album runs the gamut from piano-led tracks like "Promise To You Girl" and "Fine Line," to a self-described "daughter of [the Beatles'] 'Blackbird'" dubbed "Jenny Wren" to the contemplative "Riding to Vanity Fair" and "At the Mercy."

"We really made a lot of it up as we went along," McCartney says. "I'd try something and if it didn't work I'd try something else until it did. It was like making a go-cart in the backyard."

"Chaos and Creation" will be supported with a previously announced fall North American tour, which begins Sept. 16 in Miami.
