Describing the music of Franz Nicolay is a formidable task: it’s almost as easy to imagine the work of some of the bands he has loaned his considerable talents to in the past - most notably during his five years as a member of The Hold Steady - and then imagine the exact opposite. As proficient on accordion, saw and banjo as he is on keyboard or guitar; Nicolay’s music fuses elements of folk and punk with polka, gypsy and klezmer influences to create an articulate, joyful mix that is always entertaining.

Welcome to another show, in which Joe guides us around some of the weirder, smokier corners of the broad church of hip hop, and discussion returns to how far genre can stretch and where originality can reside in a multi-channel, everything-available-at-once world. We also take a listen to more and less authentic sounds of South America courtesy of a Brit-in-Colombia, a Colombian Brit, and a legend of British underground sounds turning Colombian sounds into house music. There's some neo-psychedelia and neo-folk thrown into the mix for good measure.

Though he first came to public attention via the Los Angeles-based Brainfeeder psychedelic electronic hip hop collective led by Flying Lotus, 25-year-old producer Lorn comes from “the middle of nowhere in Illinois”, and it's easy to see in his music a less sunny disposition than many of his comrades. Most of the Brainfeeder crew have a loose-limbed funkiness to their sound and an accumulation of sonic detail that speaks of heat and humdity.

Neneh Cherry has never been conventional. The singer and rapper's latest album is a collaboration with The Thing, a Swedish free jazz trio who have previously tackled songs by PJ Harvey and The White Stripes. If anything, the presence of Cherry has made them braver: The Cherry Thing features reworkings of The Stooges' "Dirt", Suicide's "Dream Baby Dream" and MF Doom's "Accordion". It's gutsy stuff, but it works. The album already sounds like a contender for the end of year lists.

One image remains stuck from Watch the Throne's second of five sold-out nights in London; it’s a song-long vision of Kanye West and Jay-Z – aka J Hova or just Hov – sat side by side for Hov’s “Hard Knock Life”. Hov’s words fell out of his mouth seemingly effortlessly as the track's structure emerged while ‘Ye sat in a silent, contemplative stoop - his dripping sweat and jewellery making him look post-marathon mid-set.

The masterstroke of this take on Othello was to draw its focus away from race. It might seem odd to say that of a production in the rhyming vernacular of hip hop in which the Moor was African-American and the rest of the cast were not – but it was deftly done, and as a result avoided any number of crass parallels that could have been drawn, instead focusing on the meat of the play: love and betrayal among men.

So, Rizzle Kicks, teenybop pop-hop, right? So what we’re going to get is a bunch of over-excited tweens fobbed off with pre-recorded backing tracks, a bit of choreographed dancing and maybe some balloons? Certainly the support acts, Josh Osho and Mikill Pane, while passably entertaining, adhered to a minimal set-up and plenty of basic hype man call’n’response, but Rizzle Kicks didn’t. In fact, they firmly booted pre-conceptions into touch.

A new publicly funded UK web channel for performing arts opens tomorrow morning, preparing for a major launch this weekend streaming top international streetdancers to the web audience and publishing John Peel's notes on his record collection. The channel, called The Space, is funded by the Arts Council England in partnership with the BBC, and will run for six months over and through the Olympics period as an on-demand channel to put performance out via smartphones, tablets and computers.

After a nine-month absence, during which Joe Muggs explored the world's largest natural bassbin in the Amazonian rain forest and Thomas H Green waited to receive his passport back from the Bolivian government, Singles & Downloads returns to celebrate the best in new music. From the ambient to the danceable, the glorious to the outright embarassing, we present the juiciest possible representative cross section of modern popular music.
