The Foo Fighters are back, delivering a new cover right before their album Concrete and Gold drops on Friday. The Foo’s were recently on BBC 1 and recorded a cover of the AC/DC classic Let There Be Rock. The tune is the title track off AC/DC’s third worldwide album, which hit in 1977. My favorite part of this video is seeing the intensity on Grohl’s face. At times he has to read the lyrics and then at the end he let’s it all go and focuses totally on the music. Take a listen!
