Tasavallan Presidentti (in English President of the Republic) is a Finnish progressive rock band. It was founded in 1969 by guitarist Jukka Tolonen and drummer Vesa Aaltonen. Other founder members were Måns Groundstroem (bass) and Frank Robson (vocals), previously of Blues Section. Juhani Aaltonen (saxophone/flute) had earlier played in Soulset; he was replaced in 1970 by Pekka Pöyry. Eero Raittinen replaced Robson as a vocalist in 1972, the same year as the album Lambertland was released in UK. The album was a tight fusion of jazz and folk rock with highly inventive and imaginative lyrics which charted at the number 7 position in Finland. Milky Way Moses reached number 12 in Finland in 1974. The band toured in continental Europe and the United Kingdom in 1973 and 1974, but Pöyry, stricken with bouts of manic depression, was occasionally replaced with keyboardist Esa Kotilainen on live dates.

Tasavallan Presidentti disbanded in 1974, then reunited from 2005 to 2006 with original saxophonist Juhani Aaltonen, as Pöyry had committed suicide in 1980. The band celebrated its fiftieth anniversary with two concerts in December 2019 in Helsinki and Tampere.^[1]
