"Brand New Day", arranged by Hiddo Van Os, played on the 110-key "Southsea Gavioli". I think this is a superb tune played on a superb organ!

Now I know what is meant by the 110-key being the pinnacle of Mr. Gavioli's achievements: the different registers make delightful and marked contrast to each other, but all blend smoothly into a powerful, incredibly fine ensemble. Also, the organ sounds like it's in perfect tune... and all the many reed pipes etc. have been well looked after, since I heard no squeaks and squauks as one might hear on most organs with large amounts of reed pipes. The registers seem to operate promptly, as well.
I thought it was exciting to hear a concertorgan like "Victory", which is designed for it, play modern music, but it is even more exciting to hear a vintage organ such as this do it, especially when the music is arranged with such aplomb! :D
