Rock/pop

Seattle's dark and naughty Sea Donkeys don't want you to know who they are. That's why—or because—the group performs wearing donkey masks. With a limited-edition (300 pressings), heavy-vinyl debut, The Sea Donkeys Volume 1 (out on the Sun City Girls' Abduction label) full of atonal folk dirges purportedly recorded on a boat, there's more than a little bit of playful perf-art conceit going on here. But scurvy on ya if you think that's all these anonymous asses have up their, er, donkey sleeves. The male and female voices sing of sailors, pirates, barracudas and some tramp named Lydia, recalling a sort of creaking, seaborne Black Rider-era Tom Waits or the spoken word dysrhythmia of the Shadow Ring. If you like a little stomp with your low-speed freak-out, Columbus, Ohio's Times New Viking, torchbearers for raw, lo-fi punk, share the bill.
