Spira is produced by Skuli Sverrisson, who also contributes bass and guitar. His mind-melting resume includes musical direction for Laurie Anderson, recordings with Blonde Redhead and work with artists such as David Sylvian, Jon Hassell, Ryuichi Sakamoto, Bill Frisell and Arto Lindsay. Davio por Jonsson contributes piano and guitar to the record-much as he did during Olof's busiest touring schedule nearly fifteen years ago when the two of them toured the world for months on end. There is hardly a jazz musician in Iceland he hasn't played with but lately he is perhaps best known for his close collaboration with Ragnar Kjartansson, one of this century's most celebrated visual artists.
