Two recomendations:
Greta Van FleetNew band from Michigan (although they started in 2012, its first material got published last year) which could signal the revival of classic rock. They sound great and epic. The singer is just 21 and reminds me of Robert Plant. Summary: Classic rock with a fresh air.

He is a guy from a worker's class neighborhood in Santiago and has a strong message, with some class warfare and anger but delivered in a very entertaining way. The first video is sung in Spanish and Mapudungun (language of Mapuche people, the main native group in Chile) and the second, which is one of his most popular songs and talks about the struggles of most Chileans in contrast to what the media and the elite depicts, has english subtitles. If you want to know more about Chile and its culture, I think it's a good start due to Portavoz's particular approach. (note: Portavoz means spokesperson in Spanish)
