All the club shows in Moscow have times set from 8-9, never earlier, and only later if it's a midnight rave or something. Almost all the arena shows I've been to here have 'started' at 7 though, apart from Limp Bizkit, which started at 8.
7/4 Modest Mouse, Echo & the Bunnymen
8/11 Protest the Hero
8/27 Metallica, Mastodon
