Brad Paisley has extended his H2O tour with 16 winter dates in early 2011. The newly-renamed H2O Frozen Over tour will begin on Jan. 20 in Green Bay, Wis., and conclude Feb. 26 in Nashville. Darius Rucker will continue with the tour, and Jerrod Niemann (“Lover, Lover” ) will join the lineup. The H2O tour has played to more than 750,000 fans since May. Paisley performed a free concert for 35,000 fans on Sunday (Oct. 17) in Gulf Shores, Ala., to promote tourism in the area, following the oil spill earlier this year.
