Terho is a five piece group, the musical dynamo of which are characteristic pop songs written by Teemu Ratinen and Kai Kärki. Tuomas Martikainen's vigorous drumming and Tatu Savolainen's rocking bass playing form the backbone of Terho's sound. The ribs consist of their three guitar front, from where solo guitarist Lauri Hakanen sometimes escapes into the spheres.
