Well I'm certainly very excited about it, as I really enjoyed them live. But describing how they sound... Hmmm... difficult!
I'd say Transportation is the solo album most like it, but Humania were much rockier. The set was a mixture of Ultravox covers and brand new tracks, and to be honest I think I enjoyed the new stuff the most. You already know what Billy and Robin sound like, so couple that with crisp, clean vocals, funky bass and good solid drums, and you're there.
Does that help at all? I'm afraid I'm no reviewer. Where's Si when you need him?!
