The Gudmundar Ingolfssonar Trio is, as implied, a trio of Icelandic jazz musicians made up of Gudmundur Ingolfsson (piano), Gudmundur Steingrimsson (drums), and Pordur Hognason (bass). In 1990, the band collaborated with Bjork, who naturally would stand in as vocalist, for their first and only record, "Gling Glo".
