Throughout the summer, we're following around some of our favorite bands and DJs as they head out on tour. In each installment, these road dogs will be sharing a photo diary and sharing stories about what they do, see, and hear and eat while criss-crossing the country and the globe. First up: the First Sisters of EDM, NERVO. DJs -- and rea-life twins -- Mim and Liv tell us all about their recent gig spinning in Vienna at the cuckoo bonanza that is Life Ball.

"Liv's pre-game face as she is getting ready for make-up."

"Mim getting beautified."

"Tag teaming for Liv's hair and make-up."

"Jewels jewels jewels #redcarpet."

"Suck it in, Liv! #AlexanderMcQueen"

"Last few seconds before we leave our hotel room with our stylist Jordan Grossman."

"Feeling very glamourous in our Versace and Alexander McQueen at The Life Ball -- the biggest charity event in Europe supporting people with HIV or AIDS."

"Nothing like being on the red carpet with our friends Lina and Philipp. Such a beautiful back drop at the Vienna City Hall."

"Sitting in the audience watching the amazing show; from Opera to Ballet to Ricky Martin -- it was an all round mind blowing evening for a great cause."

"Time to do what we do and get things heated up on the decks!"

"The party continues and we're wearing Sebastian Gunawan and Francesco Scognamiglio!"

"Thank you Vienna Life Ball for a truly amazing night and congratulations on a beautiful event."
