Coldplay is one of my favorite alternative bands, they actually do the required hard work to make a good music. And they make those dreamy melodies combined with poetic lyrics and a wonderful vocal performance by Chris martin. Their music is multi layered, very harmonic and uses a lot of instruments in a clever and very expressive way.
This song ” Gold in them hills” is a duo with Ron sexsmith.
Another song for them:
2- Yellow (Acoustic version)
