From deep in the swamps of Vashon comes an evening of inspired performance featuring some of the island’s most imaginative entertainers.

This weekend, Steffon and Arlette Moody will present Swamp Bottom Cabaret: a spin-off of their roving outdoor Swamp Bottom Jamborees adapted for the Blue Heron stage. The show will feature local musical groups The S Curves and The Nilbillies.

The S Curves came together three summers ago at the first annual Swamp Bottom Jamboree. Their debut performance included cocktail dresses under hip waders in the middle of a pond by candlelight, accompanied by the boisterous bass of a croaking bullfrog. Last summer they revisited that pond in a rowboat dressed in nightgowns. Unexpectedly, the bullfrog also made a repeat appearance. For this performance, they will be a little more dressed up and with some added surprises, but without the frog. The three Vashon women: Arlette Moody, Elaine Ott and Stephanie Murray are sure to send guests away swaying.

The Nilbillies are an existential bluegrass trio that doesn’t play much bluegrass. Lead billy and songwriter Steffon Moody offers his twist on the American dream, serving up both fire and brimstone. The trio is rounded out with the burly tones of Kevin Almeida on stand-up bass and funky country picking from Andre Sapp on mandolin. Expect to hear original songs that sound oddly familiar, but are mostly just odd. Top YouTube videos for The Nilbillies include “Only God Knows,” “Space Monkeys” and “Lesbian Man.”

The Swamp Bottom Cabaret is part of Vashon Allied Arts’ New Works series and will be held at 7:30 p.m. Saturday at the Blue Heron. Tickets are $16 for VAA members and students, $18 for seniors and $20 general admission.

Tickets are available at the Heron’s Nest and through VashonAlliedArts.org.
