As is his wont, Les Claypool stayed in the shadows during a sit-down set Aug. 20 in the Crystal Bay Casino with his latest project, Duo De Twang. He played country-style versions on a dobro bass of many of his fun songs, including “Boonville Stomp,” “Hendershack,” “Wynonoa’s Big Brown Beaver,” “Over the Falls” and a sped-up rendition of “Jerry was a Race Car Driver.” He and guitarist Bryan Kehoe covered “Amos Moses” and in during the encore accompanied with an electric mandolin playfully performed the BeeGee’s “Staying Alive” and Johnny Cash’s “Cocaine Blues.” The show open with the raunchy music-comedy act Reformed Whores who warned about drinking and dialing and fantasized about having man parts for a day. The sellout crowd in the Crown Room was unusually and exceptionally loquacious, which annoyed Claypool who admonished a woman who interrupted him. But the Primus front man was mostly his affable, humorous self, and he toasted the crowd with his drink after he concluded a more than 20-song performance which went past midnight. It was the first time he played in the venue.
