He has written instrumental and electro-acoustic compositions which have been performed in Iceland, the Nordic countries, U.S.A., Germany, Austria, Holland, Switzerland, China, and Singapore, and broadcast on numerous radio stations in Europe. He received a Fulbright travel grant for study in the United States, a grant from the Icelandic research council to do research on Icelandic music history, and a grant from NOMUS (Nordic Music Committee) for an Inter-Nordic computer music project.
Currently, Fridriksson lives in Reykjavik, Iceland and divides his time between teaching Music History and making Computer Music.
His music falls into two general categories; he either makes pure electro-acoustic music, working mostly with natural sounds and their movement in space, or he does live improvisations, playing electric guitar, processed through live electronics. In that field he either appears alone or with the group Icelandic Sound Company.
Sound examples can be heard on Fridriksson's SoundCloud site.
