This guy's channel is great - travels around India and the former Soviet Union, visits places most travel bloggers wouldn't go, speaks fluent Russian and Hindi.
Travels to a remote part of Russia near Mongolia to meet some Tuva throat singers... gets invited to a local school because they've pretty much never met a westerner before.
(Incidentally lots of ethnic Russians moved away from this area a few decades ago when some of the people ethnically local to the area formed an independence movement and started killing them!)
