I didn't realise how much I liked dirt. Especially New York dirt. I was going to do a rant about boutique designer hotels, which seem ubiquitous in Manhattan. Major case in point: the Gramercy Park Hotel, where I used to stay in the Nineties and Noughties. It was independent, a bit scruffy, with a great bar full of artists and rock'n'roll types and other degenerates, a perfect location and cost about a hundred dollars a night. Last time I looked it had been ponced up – fish tank in the reception, a Buddha, fancy doorknobs and good-looking but no doubt useless staff. Clean as a whistle.

I am far from the first - and in very good company - to worry about the over-commercialisation of flamenco. As far back as in 1922 Manuel de Falla and Federico Garcia Lorca, respectively Spain’s greatest composer and poet of the time, decided to organise a singing competition in Granada in which only singers from the villages were allowed to enter. The polished, preening urban stars of the Café Cantantes were ineligible. My resistance to the genre was partly to do with the Gypsy Kings, amusing enough when you first heard them, but irritating beyond words when heard for years in every wine bar in the world.

The idea of "selling out" has clung to popular music, and indeed most art forms, for a long, long time. In our postmodern techno-consumerist society it's an increasingly outdated and irrelevant concept. The book Faking It: The Quest for Authenticity in Popular Music by Hugh Barker and Yuval Taylor shrewdly takes the whole notion of selling out to pieces, from the blues of the early 20th century to Moby's deconstruction of those blues decades later. Or rather, it simply points out there was never such a thing as a core purity from which anyone could sell out in the first place. Really, Barker and Yuval say, there's no such thing as authenticity and therefore no such thing as selling out.

If you’ve never heard a Gang of Four track, you probably still know their music. Their influence is all over the Red Hot Chili Peppers, Bloc Party, Franz Ferdinand, and R.E.M to name but a few of their fans. And that's just the musical legacy. Because Gang of Four, primarily active from 1978 to 1983, if they changed anything, changed the way bands considered the role of rock music. Paul McCartney may have wanted to fill the world with silly love songs, but Andy Gill and Jon King wanted to jam the airwaves with social injustice, war and disconnected lives.

2010 saw some major shifts stirring up the UK club music ecosystem and unleashing some fascinating hybrids and variants of existing sounds out into the wild. As the hefty bass of dubstep muscled its way firmly into the heart of the mainstream, everything else was forced to rearrange its position, with some surprising results.

In the next instalment of our Year Out/Year In series, theartsdesk's New Music writers cast a critical eye over 2010, and offer some recommendations for 2011, incorporating some very funky videos. Our selection of recommended albums from the past year ranges wildly over electronica, world, jazz, indie, rock and folk. We also note some disasters and sad losses. Written by Howard Male, Peter Culshaw, Russ Coffey, Peter Quinn, Bruce Dessau, Kieron Tyler and Thomas H Green.
