Since the turn of the century, Sean Tillmann, doing business as Har Mar Superstar (above, performing “How Did I Get Through the Day” live in studio for KCMP FM the Current), has been known for his onstage antics—whether it’s slowly stripping or break-dancing or even doing both at the same time—at his sex-charged energetic live shows. But the reason he’s opened for big names like Red Hot Chili Peppers, Sia, the Strokes and Yeah Yeah Yeahs is because he’s a supremely talented singer and songwriter, aptly evident on his sixth full-length, this year’s Best Summer Ever (stream it below), conceived as a fake compilation album, featuring the one-time Broad City participant’s best songs from 1950 to 1985. “While there is often an inherent tongue-in-cheek quality to Best Summer Ever, Tillmann never fails to take the music seriously. Even when he underlines the irony, as he does on the spoken word outro to ‘Haircut,’ you can’t help but leave impressed by his highly resonant vocal chops and dedication to the process,” according to AllMusic. “Ultimately, with Best Summer Ever, Tillmann has made an album that works as both a time-traveling pop odyssey and a superb fake compilation.” Hear how the new tunes sound live, and make your weekend last a little longer, when Har Mar Superstar plays The Bowery Ballroom on Sunday night. Austin, Texas, nine-piece Sweet Spirit open the show.
