“It’s been … “ three years since multiplatinum-selling Canadian rockers Barenaked Ladies first took their rollicking roadshow Last Summer on Earth on tour, packing more than 30 arenas and amphitheaters with near sold-out crowds. They returned by popular demand in 2013, and now, more sure than ever that the Mayans were off by just a few years, they’re bringing the 2015 edition of the Last Summer on Earth Tour to L.A.’s historic Greek Theatre. Jam along to the latest songs from BNL’s highly anticipated new album (due to drop later this summer), along with their biggest hits like the chart-topping “One Week,” “Pinch Me,” “Brian Wilson,” “If I Had $1000000” and the theme song to The Big Bang Theory. Opening for Barenaked Ladies are alt-rock heroes Violent Femmes (“Blister in the Sun”) and Colin Hay of Men at Work.
