THE EXPLORERS CLUBThe Charleston-based combo's new album, Grand Hotel, as well as their early material, will get listeners looking at the copyright date. Wait. This was released earlier this year? Not the late '60s or early '70s? The band's muse lingers in an unmistakable late-'60s southern California pop vibe, with a dash of psychedelia, sprightly keyboards, happy guitars and plenty of harmonizing backing up the crooner. Lounge pop? Maybe. But the blokes are rather genuine in their love of the era, without being copycats. Brian Wilson would approve. With XVSK. $8 in advance. The Evening Muse.
