If anyone is umming and arring about this tour then I'd highly advise getting out to see Astra. They hark back to a time of bygone music for me and there's a lot to watch onstage. I saw their debut UK show a couple of years ago with Diagonal and although they were a bit nervous the performance was incredible.
New album The Black Chord is excellent although I slightly prefer the emotional melancholy of debut The Weirding.
