I like their three last records - Surrounded by thieves, Blessed Black Wings and Death is this Communion. The last one was released in 2007, and I consider it one of the best 2007 records.
Haven't seen them live, all I got is a promotional DVD which came with BBW album, with five or six live songs, but unfortunately the sound quality is crap.
I would easily check their live set, hope they come to Brazil soon.
I remember someone telling Dance Club Massacre is Geek Metal because of the looks. I you think symphonic metal cannot be combined with technical grindcore then you've got to listen to this band.
