I like Tägtgren but Pain is the one project I can´t get into, a bit too cheesy but some of his videos are great like "Just hate me" with the little robot.
Peter writes the tunes and playes every instrument on the CDs, and records and mixes everything in his own studio. The band is just for touring.
This video is also awesome:
