Knock Knock. Who is there? Bill. Bill who? Bill from Knaresborough....the Smog guy. Ah. That terrible sleeve adorns a work of rich majesty that now enjoys a 20th anniversary re-issue. Smog's previous album Red Apple Fallsshowcased the singer using ever more adventurous recording techniques and actual singing to showcase his rich brown autumnal songs. Knock Knockis a beaut. He's the Leonard Cohen of the '90s and a ladies man to match.
