Previously in our “Bonnaroo By the Numbers” series, we discovered that hip-hop acts dominate Bonnaroo’s lineup in terms of sheer volume of social media fans. Now, we’ve compiled data from Next Big Sound to create a list of the bands that are growing their fan base (Facebook, Twitter, LastFM, MySpace, YouTube, etc.) the fastest. It’s based on month-over-month percentage change leading up to Bonnaroo. The list is topped with the always-animated, experimental band Man Man, presumably because their fourth album, Life Fantastic, was released last month. The Brooklyn-based, get-the-party-started band Matt & Kim are next on the list with a 209% increase in fans, including an enormous one-time spike of 35,000 fans on May 19 — the day after the duo announced their “Sidewalks” tour and the day they released their official video for “CAMERA” on their Facebook page.
Also on the list are some up-and-comers like Sallie Ford and the Sound Outside, a Portland rock quartet that’s as comfortable playing jazz and blues as it is rock. The foursome, ranked #3 on the list, increased their social media fan base by 151%. They’ve been around since 2008, but released their debut album last month. After the jump, see all 10 bands on our list.
