Deep Dubstep

Review: From cor blimey to core nuclear reactor; Mean Streets continue their Trilogy collection with a second volume of gully comprising two more vibes from the left side. Donnie Kromestar starts the skirmish with his devastating heavyweight bash-about 'Dancehall' while P Jam & Dok flip the experience in the B with 'Funky Nandos'. A springy slice of broken beat with jazzy shimmers and cheery organs, it takes you back to Plastic People even if you didn't get to go there back in the day. Street talk.

Review: LX One fires up his Vantage machine for another joy ride around the town. As we've come to expect from the MC-turned-premiership producer, it's all about the drama and tension. 'Bloodshot' sees him teaming up with OG Youngsta for a haunted house of a jam. Dusty organs, rusty textures. Meanwhile on the B 'Seeking' goes for the jugular with its fierce symphonic stabs and end-of-the-world swagger. Heavyweight.

Review: Now this is a powerful collection of talents and dons right here... OG grime MC 9er from Macabre Unit dusts off his mic to get real over some cold, cold rhythms from no-rules basssmith Nomine and jungle don Digital. The result is two tonne iceberg waiting to trickle down your ears. Stay spinning for more coldness; Slimzee & Boylan get busy with the breaks in a way only they know how, OG Macabre Unit member Nurve brings pure bassline science before Digital tags back in with DK for a solemn but jazzy trek. Concentrate.

Review: Fresh from missives on Red Lagoon, Tribe 12 Music, ENGZ and Plantpower, Nova brings his unique brand of melodious, ultra-deep bass science to Romulus. He hits the ground opening with essential opener 'Ghosted', a collaboration with Saule that adds chopped spoken word samples and chiming, music box style melodies to a rolling dubstep beat and pulsing sub-bass. 'Glisten' adds more undulating, ear-catching synth sounds to a faster and arguably even weightier beat, while 'Win U Back' is ghostly, chunky and heavy in the best possible way. Remix-wise, we're particularly impressed by Meddem's rework of 'Win U Back', which alternates between heady ambient sections and deep, crunchy dubstep grooves.

Review: Parisian producer Ourman has been touted as one to watch many times over the last few years, with plaudits arriving for his numerous low-key, largely digital-only releases. According to our research, this outing on White Peach is his first vinyl missive - something of a landmark for the up-and-coming Frenchman. There's much to admire throughout, with Ourman combining warm, deep, sometimes punishing sub-bass and crunchy post-dubstep drum rhythms with a variety of breezy, ear-pleasing melodies and instrumental flourishes. The best of the bunch is probably the exotic title track, 'Windy', which rushes along at a notable pace and boasts what sounds like Amazonian instrumentation (but most likely isn't), though the sparkling and deep 'Rub A Thug' and skittish 'Polarised' are also top-notch.
