The three members of terrific Norwegian trio In the Country, who play the Hideout on Wednesday, all keep busy with side projects. Not only is keyboardist and composer Morten Qvenild the “Orchestra” in Susanna & the Magical Orchestra, he plays in the rock band the National Bank and works regularly with singer Solveig Slettahjell (to say nothing of his stints in Shining and Jaga Jazzist). Drummer Paal Hausken has also worked with Susanna Wallumrød as well as singer Hilde Marie Kjersem and jazz quartet Bull of the Year. Bassist Roger Arntzen is no less busy, playing in electric jazz quartet Chrome Hill and the ever-evolving Ballrogg. That last project, which he started with reedist Klaus Ellerhausen Holm, has just released its third album, Cabin Music (Hubro), and once again the group’s sound is transformed.
