Which musicians had the greatest impact on music?
Musicians, Composers, Producers, Artists, that had the greatest impact on music of all time, as I see them, listed with no particular order, might have forgotten about some.
Musorgski, Borodin, Rimskyi-Korsakov, Balakirev, Kjuee, Stasov - a "Mighty Stack" (Могучая Кучка), originally called this funny way by Stasov, the musical critic, in one of his articles. This was a crew of composers (or just visionaries) that made a very big change in the Russian opera music, ballet music. They were creators of the so-called "New Russian Music School", Vladimir Stasov as a founder, - they took quite different approaches to the old russian folklore sagas and music.
