Each week, as the 2010 Vans Warped Tour travels across North America, we will be posting a new photo gallery of live photos from the festival that Lanny Bolger took during the opening two shows of the tour in Carson and Mountain View, California.

Today we’re happy to show you the fourth gallery in the series with photos of Andrew WK, Street Sweeper Social Club, Face To Face, The Flatliners, Swingin’ Utters, Motion City Soundtrack and more.

Check out the photos here.
