From the article: To this day, some of the most complex heavy metal still comes out of Eastern Europe, a place where metal musicians often learn "classical" as their first musical language.

The cellists, Luka Šulić and Stjepan Hauser, (2Cellos) are both Croatian.

They are also classically trained, and have some very good straight classical videos out as well.

They are just awesome.

"Šulić was born in Maribor, Slovenia, SFR Yugoslavia. Šulić's father, Božo (through whom Šulić has Croatian citizenship in addition to Slovenian), is from Dubrovnik, Croatia, and his mother, Alja, is from Izola, Slovenia.[2] His father is also a cellist, and many members of his family are associated with music"

Apparently ^that^ is something people savagely fight over on the interwebs.
