A (somewhat pricey, given the 12 minutes duration) album of Backer-Grøndahl's 5 fantasy pieces Op.45 played by Benjamin Engeli on Prospero Classical is announced for digital release on 21 November - on Presto (https://www.prestomusic.com/classical/products/9802003--agathe-backer-grondahl-5-fantasy-pieces-op-45).
(I see another- even briefer - album (5.5 minutes) of her 2 piano pieces op.68, same pianist same label, announced for 14 November here (https://www.prestomusic.com/classical/products/9802004--agathe-backer-grondahl-2-piano-pieces-op-68).)
