Both Sides of the Sky is another collection of high-quality studio recordings, dating from 1968-1970. It might surprise some that, 45-plus years after his death, there's still good material that hasn't been previously released, but Hendrix was recording nearly all the time at this point, whether they were demos done in his apartment, late-night jamming with friends, working on new material, or finishing/reworking older tracks. The Record Plant recordings have been heavily bootlegged, but the truly surprising thing about this collection is the amount of material even hardcore Hendrix collectors may not have heard yet.

“Unquestionably one of the greatest pianists of all time” is how Gramophone magazine has described Martha Argerich. Her relationship with the label goes back to 1965 and her victory at the International Chopin Competition in Warsaw. Over several decades it has produced a rich catalogue of live and studio recordings, embracing a repertoire that spans three centuries, a diversity of genres, and collaborations with such figures as Charles Dutoit, Nikolaus Harnoncourt, Gidon Kremer, Mischa Maisky and Itzhak Perlman. The complete recordings for EMI Classics, Teldec, Erato and Warner Classics are featured in this box.
