Aside from yelling into friends' ears, texting was probably the most common communication technique for festival-goers at the Bonnaroo music festival. Kargo helped Rolling Stone and Garnier take advantage of this fact to create an SMS poll for the crowd to vote for their favorite band during the artists' live performances - with the winning band to be featured on the cover of Rolling Stone magazine. This extra level of natural engagement during the concert gave sponsor Garnier Fructis an excellent opportunity to personally touch every participant in post-vote messages.
