The Insolent Willies are an upstate New York roots-rock band known for their hip-shaking mix of quirky, clever original music and unpredictable covers. The band was formed in 2017 by singer-songwriters Bill Ackerbauer (acoustic guitar, harmonica, fiddle, vocals) and Frank DeVer Pullen (bass, mandolin, banjo, vocals), and now includes Paul Gavry (accordion, fiddle, vocals) and Evan Gavry (guitars, percussion, vocals), with occasional appearances by a collection of intrepid fellow travelers.
