Swanö has fronted a number of bands, including Edge of Sanity, Brejn Dedd, Unicorn, Infestdead and Route Nine.

During a jam session, when the band were soundchecking the drums, they hit upon an idea to record a short piece for fun, entitled "Guitars and Metal".

Swanö can also be heard on the albums Theli and A'arab Zaraq – Lucid Dreaming by the symphonic metal band Therion.

He also produced and played the keyboards on the Memories from Nothing album by Swedish rock band Another Life, released on Vic Records.

Swanö has also released a solo progressive death metal album entitled Moontower, on which he plays all instruments (guitar, bass, drums, keyboard) as well as providing all the vocal work.

In 2013, Swanö released with his new project Witherscape the full studio album The Inheritance, with Ragnar Widerberg as co-member, and the collaboration of, amongst other guest musicians, Novembers Doom's founder Paul Kuhr.

In 2016, the full studio album The Northern Sanctuary was released, via Century Media Records like its predecessors, featuring once again Paul Kuhr.

Despite the large amount of releases to his name, Swanö worked full-time in a music store[10] (Musikbörsen) in Örebro, near his home in Sweden, rarely doing live performances with any of his bands.
