Leif Ove Andsnes – Geirr Tveitt: Sonata No. 29 “Sonata etere” Leif Ove Andsnes presents Geirr Tveitt’s Sonata No. 29 “Sonata etere”—the only surviving piano sonata from a body of work largely lost in the 1970 fire. Widely considered Norway’s most ambitious solo piano piece, the sonata is paired here with selections from Fifty Folk Tunes from Hardanger and songs performed with soprano Solveig Andsnes. Together, the album highlights Tveitt’s distinctive fusion of folk elements and modernist expression, brought to life through Andsnes’ acclaimed interpretation.
