This is a fascinating box set, the marvelous Blossom Dearie in varied settings. I’m listening to disc 5, the first of two discs of previously unreleased Fontana recordings.
Blossom Dearie “Discover Who I Am • The Fontana Years • London 1966–1970” 6 cd box set
Disc 5: Feeling Good Being Me (Pt. 1) The Lost And Found London Sessions
@sonnymax showed me the trick to get these off many years ago.
You lift off the cover from the edge opposite the sticker by gently lifting up the piece of case that comprises the lower hinge pin. You lift the cover up and the plastic can be easily peeled off. Once done, carefully re-attach the cover.
