Balboa also has an outdoor organ that puts on weekly concerts, which I thought was quite a brilliant idea. The organ and pipes are hidden behind the large door in the photo above. While I was there, I heard an organist practicing Bach’s Toccata and Fugue in D minor, and his interpretation is interesting. If you listen to the very end of this track, the final bass notes will make your speakers rattle off the desk. You can also hear traffic, trees, and voices – not something normally heard with an organ!
