Thanks to the magic of geography, while many of us call this time of year summer, down under in Australia it's mid-winter. If you're picturing parkas and piles of snow, think again -- it's a great time for festivals, like the season's biggest, Splendour in the Grass. Welcoming heavy hitters Mumford & Sons, the National, and Frank Ocean as headliners, plus Aussie favorites (Alpine, You Am I), crowd-pleasers (Passion Pit, Of Monsters and Men), and some of our recent faves (James Blake, FIDLAR), it's no wonder last year's almost 18,000 tickets sold out in under an hour. (A limited amount of 2013 tickets are still available via moshtix.)

Byron Bay, New South Wales, Australia. July 26-28. More info: splendourinthegrass.com
