A very large bundle of new composers unknown to me were sampled and discovered through a few months of streaming this year and some were even enjoyed in various degrees

Making my personal cut, in no particular order:
Braga Santos, Goossens, Ethel Smyth, Lalo, Sauguet, Koechlin, Ibert, Braufels, Magnard, Gal (beyond the symphonies), Coleridge Taylor, Hurlstone, Joubert, Holbrooke, Kinsella, Lilburn, Stanford, Parry, Onslow, Ries, Reinecke, Krommer, Casella, Tubin, Holmboe, Weiss, Langgaard, Korngold, Wert, Ariostil, CPE Bach, Myaskovsky, Szymanovski, Bloch, Enescu, Novak, Viren, Tveitt, Gade, Czerny, Reicha, Spohr, Clara Schumann, Massenet, Campra, Escaich...
The high point of my classical year : Unlocking the Vaughan Williams symphonies, at last

A musically very rewarding year in many ways.
I intend to gradually review them more in depth again in the next year in parallel to my ongoing French exploration project.
