This is a large brass ensemble (37 brass, 6 percussionists) hailing from Venezuela. They perform in concert settings, covering all styles, including Latin, classical, and jazz. This exciting video shows those three styles, and at the end, they all stand and wildly play "I've Got Rhythm" to the delight of the audience. What a show!
The Venezuelan Brass Ensemble was formed in 2003 from Venezuela's state youth orchestra system, so they are interestingly a state-sponsored group. They got their foot into the international scene in 2007 playing at the BBC Proms, and since then they have been playing all over Europe.
