Keith Urban announces new album 'High': See full track list

Keith Urban is aiming "High" with his latest album.

The country superstar announced Friday that his forthcoming album, "High" -- his first in nearly four years -- will drop Sept. 20.

"What makes you 'high' can mean whatever you want it to mean," Urban said in a press release about the album title's ambiguity. "It might be physical, spiritual, herbal, meditative, chemical or musical, but it's definitely a place of utopia."

"For me it's my family, my friends, and this rollercoaster musical journey I'm on," he added. "Playing guitar, writing songs and the place where I feel high -- playing live. Every night I get a chance to bring an energy and a release to people."

Accompanying the announcement, Urban dropped the fourth single from the album, a song titled "Wildside." It follows previous releases "Straight Line," "Go Home W U (with Lainey Wilson)" and "Messed Up As Me."
