Concierto No. 1 (for two organs)

Josef Blanco, also known as Pedro José Blanco or Pedro Josef (ca. 1750 - 1811) was a Spanish composer, organist and harpist. His Concierto No. 1 for two organs (or harps) was discovered 1957 in the archives of music of the Cathedral of Ciudad Rodrigo.

The idea behind this recording was to bring together both Riepp organs, which are in close proximity to each other. The original plan was to record one track first and then play the second organ live during playback. However, this could not be maintained throughout the entire piece due to lack of human feedback between the two "organists". The recording was therefore split into several segments, also to make registration easier, and at the end everything was put back together again with Audacity.

Both organs:
Front/rear 50/60
Pipe detuning 20
Equal temperament, 440 Hz

Score: Edition Schott No. 4809
