Horns pitched to sound like strings; strings played low and swinging like horns; a pot-pourri of roughly Caribbean percussion – instrumentally, “The Tide Is High” is delightful escapism. Even so it’s a little bit of a let-down. Debbie Harry gives a gentle, intimate performance, but gentle intimacy isn’t really what you go to Debbie Harry for. Once she savaged her rivals and dismissed her lovers, now she’s playing a long game – with supreme and justified confidence, of course, but the woozy, flippant Blondie on show here lack the flash and fire of previous encounters. “Tide” is a postcard from a band on holiday, something to cheer up a dreary Autumn: the holiday just ended up a little longer than anyone thought at the time.
