Petter Karlsson, formerly of Therion among other bands, has joined Swedish avant-garde metallers Diablo Swing Orchestra (DSO). Petter replaces Andreas Halvardsson, who stepped down last month \"due to personal reasons\".According to the band, Petter is also a skilled songwriter so the are looking forward to see what he can add to the already twisted process of making a DSO song.
Diablo Swing Orchestra are currently rehearsing to get ready for touring later in 2010. New songs are also in the making and pre-production will probably start in the winter.
