Robin Bergh drummed in Swedish progressive metallers Amaran until he left the band in March 2004 for personal reasons. Bergh was replaced by Pär Hjulström (from Athela).
In May 2004 it turned out Bergh joined a brand-new Swedish band called Cellout, replacing Stefan Orhamn. The group, whose musical style is described as "hard but still melodic metal" with loads of "dynamics," played their first show with Bergh at Pub Anchor in Stockholm, Sweden April 29, 2004.
Bergh left Cellout again in November 2004. Replacing Bergh in the group was ex-Fatal Smile drummer Robin Lagerqvist.
