North German Rock outfit BAD SISTER, fronted by Petra Degelow, started life as a Pop Rock outfit entitled BOGART JOINT in the mid eighties. BAD SISTER debuted commercially during 1989, donating the tracks 'Running Wild' and 'Cat On The Run' to a sampler compilation of North German Rock bands called 'The Living Desert'. A brace of albums for the Hurricane label are now highly sought after by collectors.

BAD SISTER reunited in 2002 following a four year hiatus. The Point Music label re-issued the debut 'Heartbreaker' in 2003 adding two extra tracks in live recordings of 'Cat On The Run' and 'Heartbreaker'.
