Years before the relatively recent rediscovery that electronics and guitars play nicely together, Trans Am was making indie rockers nervous with their unbiased sonic experimentation. While the output has fluctuated over their decade-plus career, Sex Change emerges from the operating room with visible success. The trio has always played by its own rules, but their eighth LP sheds some of their branded irony and outwardly presents the band at their most honest. With tight instrumentals, vintage ’70s synthesizer scores, and solid post-rock groove, Sex Change shows a veteran band at last comfortable in its own skin.
