Brødrene Löwenstierne (The Löwenstierne Brothers) consists of Henrik Horge and Steinar Taarn Sande. Both participated as members of the St. Thomas band, being the background singers and rhythmic percussionists. Their band name was made up by Thomas himself during a band rehearsal. Over the years they’ve supported Thomas on various tours, both as a support band and as background singers. At The Øya Festival in 2003 they also performed live as solo harmonica players with the rest of the band. Both Steinar and Henrik are playing small parts in various St. Thomas music videos. They contributed a cover version of the St. Thomas song New Apartment to his memorial box set.
