I was looking at a a friend's facebook page and watching some of the YouTube videos he'd posted when a recommendation popped up for a wonderful arrangement of de Falla's Ritual Fire Dance performed by a group of about a dozen cellists with one soloist, Luca Sulic. I then found a very nice performance of a Villa Lobos piece from the same performance, but this time with no soloist.
The recordings were filmed in a beautiful, small hall at the Dubrovnik Summer Festival in 2005. You can hear enough of the reverb in the recording to know that it must have been incredible to witness those 12 cellos in that room. The building is just singing with the overtones of those cellos! While it might sound a bit muddy when recorded, it must have been amazing in person.
So here is a playlist with both pieces. Enjoy!
