On his sixth studio release Roulette, the prolific producer, songwriter, pianist and MC Alfa Mist has created his own sci-fi universe - a vast dystopia where themes of revenge, forgiveness and redemption loom large. Alfa Mist's albums have always tackled big themes. This time, however, he explores an imagined near-future in which reincarnation is discovered to be a potent tool linking dreams and past lives. But with this discovery comes consequences: ethical, moral and philosophical. "If reincarnation is real, how does that shape society?" he explains. "If reincarnation means accumulation of knowledge, would you share it and enable everyone to understand more about the world? Or do you struggle for power? And do some people want to stop others from remembering who they were?"Over 15 tracks, Alfa explores these ideas with heady potency. Each song is a spin of the wheel - a different song and character. The musician's signature is still there - lambent keys, intuitive groove, free-flowing jazz improvisation - but Roulette is imbued with a smoky psychedelia. An immersive listen, this album is designed "to feel" on every level, says Alfa. It also contains some of his most impressive arrangements yet - see the eight-minute title track that effortlessly flips through time signatures - "because life's like that," says Mist; it's not always linear. Roulette underlines Alfa Mist as one of the most forward-thinking composers in UK music, with poignant, plaintive melodies that lodge deep in your psyche. "I'm exploring different parts of myself," he says. "But obviously, as I grow, all of those parts change. Music is a constant; it's my state of mind that I constantly chisel and work on and make sure that's always growing and staying interested in new things. As long as I do that, it'll come out in the music."
