As Kastle, Pittsburgh-based producer B. Rich pushes the kind of soulful, low-end-centered, forward-thinking dubstep tunes that could just as easily soundtrack a night out at the club as they could the lonely walk home afterwards. Before Better Off Alone, his debut EP for Secluasis, drops, Kastle was interviewed by Media Contender in a piece that also includes a fresh mix from the DJ/producer. The 45-minute DJ set, entitled Essential Mix, is made up entirely of Kastle productions, both originals and plenty of remixes of tracks like Kanye West's "Coldest Winter," Cassie's "Me & U," and "Soldier of Love" by Sade.
