Hættuleg Hljómsveit ("The Dangerous Orchestra") was a group in which he participated along Magnús Þór Jónsson (Megas), Björk, Birgir Baldursson, and Haraldur Þorsteinsson. This group, which was active from 1990-1991 was established after the release of "Hættuleg hljómsveit & glæpakvendið Stella", an album by Megas in 1990. The band did many concerts in southwestern Iceland, in the outskirts of Reykjavík and later in rural areas of Northern Iceland. By this period Björk was no longer a member. Hættuleg Hljómsveit never released a record.
