In contrast to his previous career moves – such as signing to fellow laidback singer-songwriter Jack Johnson’s label – former aspiring skater Matt Costa took a big risk with last month’s Mobile Chateau. This time around, Costa’s self-produced, ‘60s sound is a direct throwback to the Byrds, Bob Lind and Sgt. Pepper’s-era Beatles. It’s a major improvement on the schizophrenia of his past work that aimed to emulate all his influences all at once. And while his early pop-gems will surely stay in his back-pocket, the quickly maturing Costa proves he’s come a long ways. With Threes And Nines. BRYDEN MCGRATH
