Alberto Williams (1862-1952) - Suite Argentine Nš 1 for String Orchestra
The Stringendo's Vivace Orchestra
Broadcast from a Concerto (unknown date and place)
I can provide some additional detail on the performers in this recording. The correct title of the performing group is "Vivace String Orchestra." They are the most advanced of six string orchestras operated by the Stringendo Music School of the Hudson Valley. The orchestra members are all local high school students. The conductor is Jonathan Handman. I don't recall that I was at this particular concert, but they've played parts or all of the Williams suite on several occasions. Both of my daughters are alumna of this program and I can personally attest to the quality, value, and professionalism of the program. The orchestras often play quite interesting repertoire, and much of it is on YouTube (where this recording likely came from, having been uploaded by the conductor), so you may want to search for other rarities. This particular performance is most likely from about a year or two ago.
