Sante Les Amis is a six-piece band from Montevideo, Uruguay that has been playing since 2007 and from what I can tell has quite a large following already. I only spent one day in Uruguay (riding around the back of a scooter in Colonia de Sacramento -- I highly recommend it!), but now I wish that I had spent more time exploring the country and learning about the culture.
The band's Morning Shine EP is a fun collection of electro rock tracks that you can't help but dance to. After doing some research, I learned that Sante Les Amis's live performances are known for being extremely creative, combining projected images with music. Wish I could go down there and see them perform!
You can read more about the band on their website (might be better if you can read some Spanish, although Google does a fine job of translating).
