I know what you mean. It's a real shame classical audiences focus so much on the past and neglect the wonderful composers of today. Here are a few of my favourites by still living composers;
Akira Nishimura: Tapas (concerto for bassoon solo, percussions and strings)
[Recording not found, unfortunately]
Takashi Yoshimatsu: Threnody to Toki, Op.12 (for piano and strings)
Fausto Romitelli: Professor Bad Trip
Leo Brouwer: Concerto Elegiaco
Frederik Högberg: Dancing with Silent Purpose
[Available in four parts on Youtube: [ Invalid YouTube link ]dancing+with+silent+purpose+fredrik+Hogberg]
And here is a short except from Högberg's Ice Concerto
Svante Henryson: Songs from the Milky Way
[Available in six parts on Youtube: [ Invalid YouTube link ]songs+from+the+milky+way+svante+henryson]
Nikolai Kapustin: Piano Sonata No.1, plus Toccata Op.8
Carl Vine: Piano Concerto No.1 & Symphony No.6
[Available on Youtube:
]
Steve Reich: Triple Quartet
Those are just a few and I restricted myself to living composers because there would have been way too much otherwise. Would have liked to include some Górecki, Sculthorpe, Ifukube, Villa-Lobos, and Scelsi otherwise. Oh, what the hell;
Giacinto Scelsi: Anahit
Peter Sculthorpe: Earth Cry (for Didgeridoo and Orchestra)
Henryk Górecki: Symphony No.3 - Symphony of Sorrowful Songs
(The complete work is available on YouTube but I'll only include the 2nd mvt. because I like this performance)
Akira Ifukube: Ritmica Ostinata (for Piano and Orchestra)
Heitor Villa-Lobos: Guitar Concerto
And I want to put one more in here which might not fit the topic because it's a film soundtrack but I think it's too good to ignore so here it is;
Alain Goraguer: La Planete Sauvage
(Sorry for the super long post, but you hit me where I live with this one.)
