Mexico is the name of the new album by Icelandic electronic band GusGus (pictured). If you’re surrounded by cloud-covered volcano craters, you might long for some sun and hot desert sand. And burritos instead of dried fish. At any rate, GusGus have sharpened their sense of pop and let even more agile, shimmering synths into their radiant electro-pop sound. Tonight, Berliners can find out how the newfound lightness will translate into their usually energetic live shows. Tonight’s concert is sold out, but they’ve added a second show for tomorrow with tickets still available at press time. Filling the opening slots are Kiko King & Creativemaze (Sep. 23) and Paris XY (Sep. 24).
