PORTLAND — Despite worldwide sales of 12 million albums and two consecutive Top 20 releases in the United States, David Gray went for “a complete overhaul” on his seventh studio set, “Draw the Line.”

“I knew I was gonna change things even as far back as making (2005’s) ‘Life in Slow Motion,'” the British singer-songwriter told Billboard.com. “I could feel the creative spark was sort of diminishing between the people who were involved, and it was maybe going to be time to move on and try to do something different. So that’s basically what I set about doing in a whole manner of different ways, just reconnecting with music and building a new band and a new sound.”

Gray, who released two versions of “Draw the Line” on Mercer Street Records in September, will perform April 7 at Merrill Auditorium.

One version is the standard 11-track set which includes the first single, “Fugitive,” and guest appearances by Annie Lennox (“Full Steam Ahead”) and Jolie Holland (“Kathleen”). The other is a deluxe edition that comes with an eight-track live CD recorded at the Roundhouse Theatre in London.

“This is really just a small slither of it, this album,” Gray said. “We did 35, 40 songs. There was just something going on, I think, and I didn’t want to stop it. These (songs) are what we picked to go out, sort of be the front-runners to go out and punch the world in the face.”

Concert tickets are $39.50 and $29.50, reserved seating, all ages. They are available at the PortTix box office at Merrill Auditorium or online at www.livenation.com.
