InProg was an international progressive rock festival held almost yearly since 2001 in Moscow, Russia.
The organizers of this festival called it "a festival of intellectual music", because except giving to progressive rock artists to perform they also give to Jazz and other genre artists to perform.
The official slogan of the festival is "Music for the brains".
Though there was an InProg 2007 festival planned, it did not take place because of a low financial situation.
A mix of Russian and Ukraine bands played there, including well-known Sunchild.
