Sad but true. 
This composer was born in one country (say, A) and died in another one (say, B). While in A he studied with someone who would become B's most famous composer. He was deeply passionate about, and heavily influenced by, B's culture and folklore. He died as a result of an incident in which he took part inadvertently. Oddly enough, one of his teacher's compositions inadvertently celebrate a feature of the person who caused his death.
Name the two composers, the two countries and the composition.
Sibelius, born in the Russian Empire, Grand Duchy of Finland, and died in Finland, as did Toivo Kuula, who, in a drunken fight with jägers about whether the jägers, trained in Germany, or the peasant army had a bigger role in getting Finland independent, and if Toivo Kuula's March of the White Guard was better than Sibelius' Jäger March, and also the Swedish/Finnish language question, got in a fist fight with the jägers, pulled a knife, cut (not very seriously) an officer of the White Guard, and escaped to the yard, where after falling down in the stairs, he was shot in the head by the jägers.
