Hollywoodlife.com has an interview up where B-Roc reveals some interesting info:
What do you look for in a collaborator?
B-Roc: The best music comes when we make it with our friends. The way “Classic” happened was so natural, because we knew POWERS for years, even before they were named that. We had a day off and it happened in one day. That’s how “Best Friend” happened, too [with Sofi Tukker.]
Would you work with Carly Rae Jepsen again?
B-Roc: Everyone loves that song! I don’t know. I worked on something at a writing camp that [was going to be] used for her album — a really rad song that I love. Hopefully it’ll be on her record. Other than that, she’s doing her own thing, working on her new album. She has so many songs! She’s sitting on hundreds of songs.
