Back in the days of acid house, it wasn't just drugs, new music and wideboy promoters with slicked-back ponytails and mobile phones the size of Essex that fuelled the party scene. Just as important was the surplus of empty commercial properties created by the recession of the late 1980s, making the setting up of soundsystems in disused warehouses and quarries a doddle. This event, part of the Ninja Tune label's ongoing 20th birthday celebration, wasn't an illicit rave as such, but its use of a previously derelict set of six railway arches in the middle of a recession went some way to recreating a bit of the old atmosphere.

This month's extraordinary, rich and strange releases are led by Ninja Tune's 20th-anniversary album of new tunes and remixes ("hard to know when to stop throwing the compliments"), Robert Plant's new band ("puts most vintage rockers to shame") and the new one from fellow veteran and "louche Lothario" Bryan Ferry. There's electronica from Magnetic Man and theartsdesk writer Joe Muggs's new Dubstep Compilation, cyber-pop from Tinie Tempah and a terrific new project featuring musicians from Eritrea. Stinker of the Month is the Motown covers record from Phil Collins. Reviewers this month are Joe Muggs, Thomas H Green, David Cheal, Kieron Tyler, Russ Coffey, Graeme Thomson, Adam Sweeting, Marcus O'Dair, Howard Male and Peter Culshaw.

Mark Ronson & The Business Intl, The Bike Song (Sony Music)

There are ways and ways to make novelty retro-pop. Mark Ronson, for example, has absolutely nailed it here. This song, with its almost unbearably sunny Lovin' Spoonful-styled harmony vocals slathered over an early-Nineties pop-hip-hop breakbeat with jaunty raps from Spank Rock, should be awful – should be so calculatedly faux-naif it makes you hurl – but it's just done with so much invention, so much out-and-out glee and such great hooks that it's completely irresistible and delicious.

Dubstep is everywhere – and if you will excuse a little self-promotion I have, in my small way, helped this state of affairs come about. The bass-heavy, rhythmically exploratory and very British electronic dance music genre has now – via Magnetic Man and Katy B – proved it can produce bona fide top-10 hits, and it has become the de facto sound of every summer festival to boot, while still keeping both feet in the underground clubs from whence it emerged.

This month's most fascinating or interesting new CDs filtered out by theartsdesk's reviewing team includes the controversial but fun new one from M.I.A., "the first real pop star of the 21st century" Janelle Monae, and the latest from Arcade Fire. We go to Nashville for Caitlin Rose, Dakar for Cheikh Lo, Ghana and Togo for Afro-Beat Airways and everywhere for the sadly missed Charlie Gillett's last compilation. There's some terrific new piano jazz from Vijay Iyer and several groovy videos. CD of the Month is the "re-invention" of Welsh belter Tom Jones. Our reviewers are Howard Male, Graeme Thomson, Adam Sweeting, Joe Muggs, Peter Culshaw, Bruce Dessau, Thomas H Green and Marcus O'Dair.

Today Rinse FM, London's leading pirate radio station, announced it has been granted a legal broadcast licence after 16 years of illicit transmissions. It's almost impossible to overstate how potentially momentous this event is for the UK's most vibrant and promising music scenes, and what opportunities it presents for artists, personalities and record labels ranging from the deep and experimental to the most flagrantly commercial. From the rumbustuous, teen-friendly fun of Scratcha's breakfast show to the experimental electronic jazz and funk of Alex Nut at Saturday lunchtime to various hard and dark grime and dubstep shows - as often as not playing exclusive music fresh from the hard drives of its creators that may never even become commercially available - it is a brilliant representation of London's cultural vitality in the 21st century.

Quasi, Bye Bye Blackbird (Domino)

The "Bye Bye Blackbird" on offer here is not the jazz stalwart favoured by everyone from Peggy Lee to Miles Davis. It is, instead, a garage guitar-pop concoction from perennial underdog trio Quasi from Portland, Oregon, that prolific centre of American indie guitar raucousness. At the core of the band, ex-husband and wife Sam Coombes and Janet Weiss have always appeared happy, throughout eight albums, to veer into wilful lo-fi messiness whenever their natural aptitude for a tasty melodic song threatens to interfere. This time, though, they've blown it.

A little revolution is taking place at the top of the pop charts. UK artist Tinie Tempah's rap track “Pass Out” has had two weeks at number one, and at the time of writing looks very much like it may successfully fight off Lady Gaga & Beyonce's spectacularly-hyped “Telephone Thing” to make it a third week on top.

Amongst all the musical benefits for the victims of the Haiti earthquake, one club event which took place on Wednesday night in London stands out as a small, but powerful, beacon of hope. Not because it could rival Jay Z and U2 for levels of funds raised, but because it represented levels of commitment, self-motivation and unity among the capital's multi-ethnic youth subcultures that flies in the face of scare stories about gang violence, drugs, educational failure and all the rest of it. Raising well over £10,000 for Haitians, the entire event on Wednesday night at the club Den/Centro was pulled together in a mere three days by journalist and activist Chantelle Fiddy, promoters SOMEnight, and DJ Stanza of the Watford-based dubstep and grime label True Tiger, and went without hitch despite featuring on its diverse bill many grime rappers and DJs who find it difficult to perform in London due to police pressure on promoters. theartsdesk spoke to a dazed but happy Chantelle Fiddy yesterday to discuss the ramifications of the event.
