My Sister's Machine was a grunge band from Seattle, Washington that formed in 1989, consisting of members 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.
In 2010, the group reunited to headline the Layne Staley Tribute and Benefit Concert. Pollock had previously played guitar in an early incarnation of Alice in Chains (stylized as Alice N' Chains) that also included Staley.
