My wife found the video below on Facebook of a group performing the classic Eagles song, "Hotel California". I've listened to it a number of times now and I've done some research trying to find out more about who the group is that's performing. The group's name is "Vocal Sampling". I tracked down this little bit about them.
Vocal Sampling may sound like a full salsa band - but in reality their unique sound is created by a six piece all-male Cuban a-capella group. With minimum technology, they use only their voices, their cupped hands and their own bodies to create a full range of timbres and textures. All the instruments of the Latin Orchestra - percussion, horns, keyboard, bass - are vocally reproduced with astonishing accuracy for their hugely entertaining set of classic boleros, rumbas, and salsa, as wells as more contemporary compositions.

Although the entire performance is impressive, on the song "Hotel California", I believe the stand-out is the electric guitar solo from the guy in red.
Through looking for more performances by the group I also came across this performance of "Every Breath You Take"
And for an overall introduction to their breadth of talent check-out this mix. I believe this video is the entire performance available online.
