2018 release. Onion produced by The Black Keys front man Dan Auerbach at his Nashville studio finds a finely tuned and tour-tested band stretching out from the 60s-inspired surf inflected rock that has defined their previous releases and delves into genres including soul and psychedelic pop. On Onion the band explores themes of origin and self-determination loss and recovery and the power of community to heal after tragedy. quot;It s okay for people to interpret the songs quot; Shannon Shaw says. quot;You can put your own story into it if that helps you heal. I just want people to feel something whatever it is.quot;.
