Side2.no recently had an interview with Norwegian singer/songwriter Tom Hugo Hermansen, who released his debut album Sundry Tales earlier this month.

In addition to his solo project, Hermansen is also a member of the covers band Radiojam. The interview mentions that Radiojam was once hired as a backing band for Morten at a private event.

“He came to Kristiansand to rehearse with us, and he wanted an authentic feel to it. So we rehearsed in an old, worn-down rehearsal room at Samsen Kulturhus. Playing with Morten was great, and I’d be happy to do it again”, Hermansen says.

“And he liked my EP and said it was annoyingly good. Annoying because there are always new artists trying to challenge his own music. But I have quite a while to go until I’m on Harket’s level.”

The interview doesn’t specify exactly when this performance took place, but the EP Hermansen mentions was released in 2009.
