It may be the first TomorrowWorld ever, but the inaugural festival is already bringing more than 300 acts to the United States.

Besides the usual heavy hitters such as Tiësto, Afrojack, Steve Aoki and Diplo, a majority of the stages round up other acts that haven't broken through to the mainstream market quite yet. MTV News caught up with some of EDM's greatest veterans to get some advice on which "artists of tomorrow" we should keep an eye on this weekend.

Not surprisingly, the Los Angeles-based group GTA came up more than once. Both Steve Aoki and Martin Solveig are enamored by the two producers, and according to Aoki, "everyone" is playing their records right now. Another performer at TomorrowWorld and "artist of tomorrow" pick from Aoki was Dirtyphonics, a group of four producers from France that only produce "insane bangers."

Alesso naturally vets for his close friend Otto Knows, who recently worked on some new music for the legendary pop-star Britney Spears, and Alesso promises his new releases will be just as incredible.

But by far the most interesting projection came from EDM superstar Afrojack. When asked about an "artist of tomorrow," without skipping a beat, he declared his good friend Hardwell -- an unexpected name since he is far from a new or underground artist. He joked that despite this, and the fact that he is not signed to his label, he guarantees in the next two years, Hardwell will soar in the industry, predicting David Guetta-level awareness and success.

Although Otto Knows can't make it, you can catch the rest of these acts this weekend in Atlanta, Georgia, performing at TomorrowWorld. Keep it locked to MTV News for full coverage!
