There are cover bands, and there are COVER bands.
This, no joke-is probably the best cover band in the world.
The great hits of the 1960s and 70s were no accident-they used the best musicians, the best arrangers, the best singers etc.

Here comes a band fronted by two 15 year old girl vocalists, who can hit the harmonies of the Mamas and Papas, CSN, backed by superb musicians who meet and occasionally surpass the original versions.

It is no accident why some of their Youtube videos have 2.5 million views, and a personal congratulation from Graham Nash himself.

For instanct.... look at this and see if you are not a fan. This was their first song from their first performance EVER!
