Ragna Kjartansdóttir was one of the pioneers of Icelandic hip-hop, being a founding member of Subterranean, the first real Icelandic rap outfit. Since those early days she moved on to study and work as an audio engineer before staging a comeback as Cell7. The level of audience engagement in her concerts is spectacular as Ragna has a unique way of creating a great wibe with her energetic performance.
