Hellbergs career started when his band Nymphet Noodlers was discovered and later produced by Ebbot from The Soundtrack of our Lives.

Former Nymphet colleagues Hederos and Hellberg recorded 8 cover songs meant to be a demo to get gigs in bars in 1996.

Ryan Adams discovered the duo when he was playing his first concert in Gothenburg, and he brought them with him on a European tour as Hederos & Hellberg's second album, "Together in the darkness" was released in 2001.

After Dregen's departure from The Hellacopters Hellberg was drafted as a live member before Robert Dahlqvist joined as a full-time guitarist.

Hellberg later worked with Hellacopters front man Nick Royale and Scott Morgan's soul band The Solution and guitarist Robert Dahlqvist solo effort Thunder Express.
