Grok was a Hamilton "super-group" of sorts, being largely a collaboration between brothers Scott Brodie (bass, vocals) from Inchworm (and later Girlinky) and Grant Brodie (keyboards) from (amongst other bands) Dribbly Cat Attraction. Other members were Chris Fish (guitar) from Love and Violence and Department of Corrections and Max Ward (drums), ex-the Sandbabies.
Grok reformed in 2006 with a substantially different lineup, with only Scott Brodie remaining from the original. The new Grok (sometimes called Grok 2) are based in London and include three members from Girlinky, who stopped playing in 2005; Scott Brodie (bass and vocals), Rob Talsma (drums) and Chris Ayles (guitar). Two keyboard players from the initially reformed Grok, Jayne and Dan, have since been replaced by three new keyboard players. During 2007 Grok spent time in a recording studio, which resulted in the release of a single,Song for Europe in May 2008, and an album titled Ruined Music for Everyone in June 2008. Grant Brodie has contributed to the album via the internet from New Zealand.
