BIS presents a disc of organ works from Finnish composer Kalevi Aho. Aho is known principally for his large orchestral scores but he came to writing for organ via the orchestra by featuring it as the solo instrument in his Eighth Symphony. The Finnish organist Jan Lehtola urged Aho to write the Symphony for Organ after playing the organ part for the Eighth. The subtitle Alles Vergängliche (‘All that is perishable’), comes from the end of Goethe’s Faust, and alludes to the symphony’s Faustian character The Three Interludes depicts a mid-summer journey on the Arctic Ocean, when everything, in the absence of night, was ‘bathed in an endless blue-tinged light’.
