Australian country singer Travis Collins breaks hearts with tender ballads, then rattles the walls with twangy rockers. The title track of his 2005 debut album, Start the Car, roared off the grid, punctuated with blasts of soulful horns and wailing backing vocals. Collins soon developed into a restless and versatile artist. The same guy who declared his love of winding roads against the choogling boogie of “Curves” later duetted with Amber Lawrence on a rousing love letter to Australia called “Our Backyard” and addressed the ravages of depression on the resonant, heart-tugging “Call Me Crazy”.
