Mahjongg shows are a glorious mess—on the band's last visit to Seattle, they crowded the Rendezvous's small stage with spray-painted computer towers and television monitors—and their music is every bit as bizarre, a chaotic mix of dance punk, electro funk, Afro pop, and militaristic noise. Their latest album, Kontpab, captures the energetic mayhem, cryptic patterns, and tense movements of their live shows. Calvin Johnson and So Many Dynamos open.
