Thirteen years can put a hell of a lot of wear and tear on even the hardiest of rock ’n’ roll bands. But don’t be fooled by all those hundreds of thousands of miles on Micky & the Motorcars’ odometer: pop the hood of Hearts From Above, the long-running Austin band’s seventh album, and you’ll find a brand-new engine, fine-tuned and good to run for at least as many more miles still ahead. And behind the wheel? Two brothers — Micky and Gary Braun — who by their own admission haven’t been this fired up about playing together since they first rode south from the Whitecloud Mountains of Idaho to stake their claim to the Texas and wider Americana music scenes.
