A brand new piano reduction constructed by Stephen Street from Bottesini's manuscripts of the I Puritani fantasia. Alongside the duetto version for orchestra with Cello and Double Bass soloist, Bottesini went on to arrange the I Puritani fantasia for solo double bass and piano. The edition for piano and bass has been reworked back to the earlier duetto version, where the earlier orchestration has been reduced on to piano in the differing areas, giving an authentic piano reduction made from Bottesini's ideas.
