My Sister's Machine was an American rock band from Seattle, Washington, formed in 1989. Its members were Nick Pollock (lead vocals, guitar), Owen Wright (guitar), Chris Ivanovich (bass guitar), and Chris Gohde (drums).
This band recorded and released two albums, Diva and Wallflower, before they broke up in 1994. They reunited in 2010 to headline the Layne Staley Tribute and Benefit Concert that year as Pollock had previously played guitar in an early incarnation of Alice in Chains, the glam metal band Alice N' Chains that also included Staley.
