CHICAGO — After banging back-to-back sets at Lollapalooza by Zedd, Madeon and Porter Robinson, MTV News caught up with PR this past weekend and he made a major revelation about a new tour concept he and Zedd have coming up.

"We've been going back and forth on this a little bit, but I think the final, official name of the tour is 'Porter Robinson & Zedd Present: Poseidon — The Back-to-Back Tour,' " Porter revealed. " 'Poseidon' is the name of the song we are doing together. It's going to be sort of the theme of the tour. We wanted to include 'Back-to-Back Tour,' to make it clear that it's not Zedd opening for me, or vice versa. We are playing together.

The coming together of Porter & Zedd makes sense, really. When not performing, the two buddies are often seen hanging together. They share an appreciation for musicality over the 'hardest drop,' and have an endearing respect for one another's abilities. So just what will their song "Poseidon," sound like? We'll let PR do the talking.

"The song is pretty," Porter said. "It's kind of like disco chords on trancier sounds, with a nice topline, and a really nice crowd vocal. Me and Zedd recorded it together. We did a 100 takes of like three guys going, 'Heeeey,' and we turned it into this massive crowd vocal, and it turned out really well and sounds really cool. I think it's something where I'll be able to pull the fader up and everyone will be able to sing along."

As for the tour, Porter couldn't reveal any dates just yet, as details are still being finalized. But he did dish a bit on what fans can expect from a 'Back-to-Back' Tour with Zedd & Porter Robinson.

"Me and Zedd have discussed this a little bit, but we don't have this set in stone," Porter said. "I would love it to be just purely for the fans: A Porter track. A Zedd track. A Porter track. A Zedd track."

"I remember seeing Doctor P and Flux Pavilion and between the two of them they have so many hit songs," he continued. "They just slap them back and forth for an hour and a half and the crowd screams every time they recognize something. To me that's awesome! So I would love to capture that with me and Zedd. But we also have a lot of songs that are not by us that we have a shared huge appreciation for and we plan to improvise a lot. We want to get up there and be stupid and have fun."
