In its best moments, Parallel Memories has a lovely, lullaby-ish sweetness we don't typically associate with London grime. "Hot Air" is wonderfully wispy, with quiet synths that dissipate into a powdery reverb chamber. "Wandering Glaciers" crawls along with just enough melody to keep your attention, as if it were meant to merely tease. There's an endearing music-box quality to "It Takes Hold Of You," and Mitchell's rework of Dark0's "Sweet Boy Code" is one of the prettiest tunes to come out of the Boxed camp, though that one also features periodic vocal gasps, a device that becomes a problem elsewhere on the album. Sampling little snippets of R&B can add a lot to a giddy rhythm, but on Parallel Memories they crack the gorgeous facade of tracks like "Don't Leave" and "Denial" to the point of distraction.
In a way, it feels like Mitchell is tip-toeing all the through Parallel Memories. "Feel Don't Ask" and "It Takes Hold Of You" have all the elements of slamming grime tunes, but spaced out to a slow-faucet drip. This is interesting in its own way, but as Parallel Memories goes on, it begins to feel like Mitchell hasn't done much to his formula aside from slowing it down. He's an excellent producer with an unusual ear for melody, so it's a nice effect at first. But for something as weighty as a debut album from a hotly-tipped artist, Parallel Memories feels a little too light for its own good.
