Rustie - Bad Science EP (Wireblock)

Enjoyably blotto dubstep-not-dubstep from Rustie, a young Glaswegian man who looks like a younger Glaswegian man, and once wrote a track called Inside Picachu's Cunt. Of all the current so-called "wonky" producers, Rustie is top of the pile, thanks to a hypercolour sound palette of eight-bit bleeps, gun-clap percussion, and laser synths that sound like Sonic The Hedgehog twirling a stripper's pole. Importantly, though, it's the way he stitches sounds together - for the floor, not the chin-strokers - that's the secret of his success.

Dan Black - Symphonies (Polydor)

Originally, Symphonies was Hypntz, a voice-and-beats cover of Notorious BIG's Hypnotize, until Biggie gave Dan Black a really stern look from beyond the grave and Dan decided to make it about something else instead. Happily it hasn't spoiled the song itself, wide-eyed soul searching conducted somewhere in the upper atmosphere that weaves Black's angelic coo, glimmering John Carpenter synths and the drum break from Rihanna's Umbrella into something as wispy and beautiful as distant cumulonimbus.

Frankmusik - Confusion Girl (Island)

Welcome to 2009, where you can wear your hair like the victim of a prank on a school field trip, and dress like you did your best in a pitch-black charity shop, but still get to give Holly Valance a little kiss at the end of your video. Not wholly sure about Confusion Girl; Vincent Frank's forthcoming album is inventive electropop dotted with all manner of glitches and appealing idiosyncrasies, but this smarmy re-fix of his original blog hit feels like he's looked through the papers, realised he's not a star yet, and hammered at the preset marked "lowest common denominator". He sells himself short.

Chipmunk - Diamond Rings (BMG)

While it's a little disappointing that all grime really needed to do to make hits was to quit the stuff about shanking people and start writing about objects selected from the jewellery section of the Argos catalogue, it's hard to dislike 18-year-old London MC Chipmunk. Look at him, done up in his little tuxedo. He's like a Dizzee Rascal action figure. And while Diamond Rings takes a somewhat diluted route to success - chugging soul backing, diva-crooned hook - Chips goes on about how great he is with an easy charm, and you would feel a spoilsport to argue.

VV Brown - Shark In The Water (Island)

"Baby, there's a shark in the water/ I caught them barking at the moon," sings VV Brown, and we are immediately confronted with so many questions. Has VV got sharks confused with dogs? Is she stranded in some terrible menagerie? Is this song perhaps beamed back from futuristic times, when sharks are extinct and scientists can only speculate on the noises they might have made in the wild? In all this confusion, one thing is quite sure: I will never listen to this single again.
