Johan Frandsen (born 9 September 1982 in Stockholm, Sweden), is the frontman guitarist, main songwriter and lead vocalist in the Swedish rock band, The Knockouts.

As well as being the main songwriter and frontman of The Knockouts – from 2004 Frandsen was the lead guitarist with internationally respected Swedish rockabilly band, The GoGetters, having toured over 300 dates with shows all over Europe and the USA.

Performing hundreds of jam-packed and sold-out shows, The Knockouts have respectively gained a reputation of delivering, what is now described as a “cocky punk rock” sound with an aggressive rockabilly technique.

The success of their album scored them national support and the slot on the Hultsfred Festival, playing in the same year as bands such as Iggy Pop and Rocket from the Crypt.

After devouring two years' worth of gigs, and with a different way of looking at the Swedish punk rock scene, and following from the success of Skyline Supernova, in 2003 the trio went onto solidify its sound with the introduction of longtime drummer Ted Jergelind.

It is just so tight, intense, messy, expressive, powerful, explosive...[6] The official single, "Under the Light"[7] is attracting radio play and reviews both in Scandinavia, USA and Europe.

This album received radio plays and reviews; ... the catchiness of the beats and melodies grab you, the lyrics hold on tight and refuse to let you go ...[9] The official single, ...'Days Long Gone' hurtles out of the speakers with a confidence and energy that tells me everything I need to know about this record and that is it's going to compete and there's a strength in the outstanding playing and songwriting that places this Scandinavian three piece right at the top of the pack...[10] The album also featured Kevin McKendree on piano on the song “Stars of Us”.
