The 2015 Deschutes County Fair kicks off this week with concerts from two performers in the midst of transitions.

Oklahoma-based modern hard rockers Hinder — best known for sludgy power ballads and party anthems such as “Get Stoned” and “Better Than Me” — returned this year with its fifth studio album, “When the Smoke Clears.” The record is typical Hinder with the exception of a new face in the band: lead vocalist Marshal Dutton, former guitarist for Texas rockers Faktion, who offers a more nasal take on founding belter Austin Winkler’s husky growl. The band will bring its rejiggered lineup and new tunes to the fair Wednesday evening.

Then, the first of the fair’s traditional two country acts, Martina McBride, hits the stage the Thursday night. The three-time Academy of Country Music Top Female Vocalist and four-time Country Music Association Female Vocalist of the Year shook things up on last year’s “Everlasting,” a collection of reimagined R&B and blues tracks.

And while McBride’s hits such as “Independence Day” have been getting an “Everlasting”-style makeover live, McBride is looking ahead to recording new music for her new record label, Nash Icon.

Both concerts are free with fair admission — $12, $7 for children ages 6 to 12 or free for ages 5 and younger — but require a concert pass, available at any Central Oregon McDonald’s Restaurant from 2 to 7 p.m. Wednesday. America and Joe Nichols are coming up next weekend, so stay tuned.
