Most bands can’t keep it together for one year, let alone one album, but the Legendary Pink Dots have kept on keeping on for more than 15 years and more than 40 official releases (not including numerous, sundry side projects). Frenzied fans have followed LPD and their unflinching do-it-yourself ethic through album distribution difficulties, changing musical trends, and an ever-revolving door of musicians, but if the band’s music had sucked, no amount of good cheer could have sustained a group for so long. In the words of co-founder Edward Ka-Spel, LPD’s “terminal kaleidoscope” music is “rather like a drowning man seeing his life flash before his eyes.” Dark psychedelia, gothic folk, death dub, and apocalyptic lyrics make up Nemesis Online, the Dots’ latest aural assault on mental stability. LPD bassist and percussionist Ryan Moore’s Twilight Circus Sound System opens at 9 p.m. at the Bayou, 3135 K St. NW. $10. (202) 333-2897. (Christopher Porter)
