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.

Tonight on Channel 4, a new music series begins with a fantastic premise. A group of music obsessives drive around the USA in a London black cab, finding interesting musicians and recording them performing and talking in the back of the cab. Sounds a little bit like the 2008 Stephen Fry in America series, doesn't it? Well maybe, except Black Cab Sessions has been broadcast online since 2007.

Where the creative interconnections between hip hop, jazz and soul are concerned, Robert Glasper proves himself a master on Black Radio. Featuring an impressive roll call of guest singers and rappers, the pianist has finally made the album which brings together all of his musical predilections into a single whole, and the results are outstanding.

Well, who could have predicted that? For once the Grammys proved that the US recording industry establishment is up for the challenge of reflecting the sense of a world in social and cultural flux by throwing surprise after surprise, bombshell after bombshell, at its shocked audience. It was a night of victory for the underdogs and the radicals, a sense of musical revolution in the air, with all bets off. OK, no, of course it wasn't. But we can dream, right?

Naturally 7 represent the point where close-harmony singing, beatboxing and spookily accurate instrumental imitation meet. The US septet call it "vocal play" - the voice as instrument - and last night they sent dopamine levels soaring in the Barbican. The group conveys the beat-driven swagger of hip hop, the freewheeling improv of jazz and the trenchant emotion of soul, often within the confines of a single song. Their arrangements, courtesy of MD Roger Thomas, possess such textural imagination and technical finesse that they're able to traverse genres seemingly without artifice.

The dust will eventually settle around the flapdoodle about withdrawn albums, whether Lana Del Rey is authentic, a fabulist construct or rubbish live. And when it does, this, the debut album, will be left. There’s no doubt that “Video Games” and its follow-up “Born to Die” were terrific singles, sieving the existential drift of Julee Cruise and Chris Isaak through a hip-hop sensibility. The package was completed by the irresistible Del Rey voice, a downer-dosed Stevie Nicks.

I first heard Zed Bias's Biasonic Hot Sauce – Birth of the Nanocloud last autumn. He may have been one of the key players in the London-centric sound of UK garage, but he was never of that scene. Based in Milton Keynes through the first phase of his career, he releases through a Brighton label and is now resident in Manchester.

I've seen some genre intersections in my time, but gangsta ambient takes the biscuit. Baghdad born South Londoner VersA Beatz began as a grime producer, but like many has moved from that genre's hyped-up energy into the slower, more menacing electronic “trap beats” of hip hop.

Debut albums often set the bar high. How are you going to top a Psychocandy or a Piper At The Gates of Dawn? The answer is, not easily and, with rare exceptions, not at once. All those ideas that had been growing forever splurge out in those first excited studio sessions, years of passion and imagination explode into the open and the thrill carries to the listener.
