Nami started as a three piece in 2007. All the members had been playing in different bands for years, but now they wanted to try something new. While not knowing what exactly they were looking for, they started jamming. After going through various genres, they settled on post‑rock. Now they make loud, beautiful, noisy, spacey music, mixing elements of prog, electro, shoegaze, psychedelic and pure noise. In October 08 Vegard Sjøen joined them on bass and keys.
