Matthew McConaughey shows off his vocal skills with his latest role in The Rivals of Amziah King. On Friday, Lakeshore Records released the single and music video for “Quill” from the original motion picture soundtrack, performed by the Oscar-winning and co-star Ben Hardesty, also featuring Miranda Zickler, Angelina LookingGlass and Andrea Pister. Set in the backwoods of Oklahoma, The Rivals of Amziah King follows the musically gifted Amaziah King (McConaughey) and his bluegrass-playing band of misfits while overseeing the premier honey-making operation in town. But the honey game is ruthless, and Amaziah’s rivals threaten to destroy everything he has built. Premiering Aug. 14 in theaters, the Andrew Patterson-written-and-directed drama also stars Angelina LookingGlass, Cole Sprouse, Jake Horowitz, Tony Revolori and Kurt Russell.
