Dan Swanö, (born on the March 10, 1973, in Finspång, Östergötland, Sweden), is a Swedish music producer, vocalist, guitarist, bassist, drummer and keyboardist, regarded as influential in the underground death metal, progressive metal, and progressive rock communities, with a small but devoted cult following for his numerous works.

Swanö has fronted a huge number of bands, most notably Edge of Sanity, Nightingale, Brejn Dedd, Unicorn, Infestdead and Route Nine. He has also been a member of Pan.Thy. Monium, Katatonia (for whom he played the drums), Ribspreader, lead guitars and drums and most recently a member of Bloodbath, playing drums on their first EP Breeding Death and debut album Resurrection Through Carnage. He moved to guitar for the release of Nightmares Made Flesh, which occurred when vocalist Mikael Åkerfeldt (Opeth) left and was replaced by Hypocrisy's Peter Tägtgren. Upon the completion of Nightmares Made Flesh, Tägtgren left and the vocalist position was once again vacant. Dan is no longer in Bloodbath as his "services are no longer needed" because he cannot tour with the group.

In the two man band 'Sörskogen', he was playing drums, keyboard and bass, while Åkerfeldt took care of vocals and guitar. Since the project was "just for fun", they never got serious about working on a release and officially only wrote one song, 'Mordet i Grottan', which was published on the internet with Åkerfeldts permission.

1998's Moontower combines death metal and progressive rock in a way somewhat reminiscent of Opeth despite leaning more heavily on keyboards than most metal bands. All of the instruments were played by Dan himself (who also produced the effort), and it stands as an impressive foray into progressive rock.
