Mark Selby, the songwriter behind the Dixie Chicks’ “There’s Your Trouble” and Kenny Wayne Shepherd’s “Blue on Black," is dead. The singer-songwriter died after a battle with cancer on Sept. 18 at the age of 56.

Over the course of his career, Selby, an Oklahoma native, worked with a slew of artists, including Wynonna Judd, Trisha Yearwood, Johnny Reid, Jo Dee Messina, Keb’ Mo’ and Lee Roy Parnell. Some of his other notable charting tunes include Tammy Cochran’s “I Cry” and Pinmonkey’s “Barbed Wire and Roses.”

The talented singer and session guitarist was married to Tia Sillers, who co-wrote Lee Ann Womack’s Grammy-winner “I Hope You Dance.” He released a number of well-received solo albums during his nearly thirty-year career, the most recent being 2013’s Blue Highway.

CMT describes his style as bluesy, leaning on artists like Eric Clapton and Jimmy Page for inspiration. His well-established guitar skills appear on albums from Judd and Reid, in addition to Kenny Rogers and others.

Written with Sillers, “There’s Your Trouble” was a No. 1 hit for the Dixie Chicks — their first ever, in fact — earning them a Grammy for Best Country Performance by a Duo or Group With Vocal.

Selby’s family asks that in lieu of flowers, donations be made in his memory to MusiCares, a nonprofit arm of the Recording Academy that provides support and relief for musicians in times of crisis.
