Ash Bowie (born circa 1968) is an American musician.
In 1990, he formed the band Polvo (as a guitarist and vocalist) along with Dave Brylawski, Steve Popson, and Eddie Watkins. Polvo was influential in the then-thriving indie rock scene in the United States. In 1995, he became the bassist for Helium, after their previous bass player left the band. Both bands broke up in 1998. In 2000 Tiger Style Records released the album Yesterday ...and Tomorrow's Shells, a collection of Bowie's four-track home recordings, under the name Libraness. He occasionally plays guitar in the band Fan Modine and bass guitar in the BQs, and he has indicated that two new Libraness albums are nearing completion.
Polvo reunited in 2008. They toured and recorded a new album, In Prism.
