Wilco show why they're the best live rock band in America right now with a clip from their forthcoming album, The Whole Love, which shows the band recording their new track, "Art of Almost", at their Loft Studios in Chicago.

If you are going to disown your overbearing, religious family, then head first to Sacramento, California. That is how Julie Ann Bee escaped, first by falling in with some "witchy, objectionable" types, she says, before reinventing herself as Sea of Bees, a studio project now bearing fruit as a live proposition.

Such is the interest in Sea of Bees that revered stars of the indie scene, Jason Lytle of Grandaddy and Colin Meloy of The Decemberists, are fans. The latter even listed California singer-songwriter Julie Ann Baenziger's debut album, Songs for the Ravens, as one of his top albums of last year.

At last, a musical without the jazz hands, and a folk opera made in heaven

Musical consensus is dull, but there were – as noted in many other best-of-2010 lists – a handful of great albums that were hard to ignore this year.

As we publish HMV's Poll of Polls on 2010's critically acclaimed music, Kunal Dutta notes the gap between the pundits and the punters

The strikingly austere tone of the cover photo of Berlin-based Danish composer Agnes Obel is borne out in the contents of Philharmonics, in which limpidly evocative piano instrumentals in the vein of Ludovico Einaudi, some tinted with cello, organ, harp or celesta, blend seamlessly with Obel's delicately dusky harmonies, floating like feathers in songs such as the haunting "Riverside" and "Beast".

Now you see them, now you don't, but that's magic

Set on one of the most beautiful festival sites, the Glanusk Estate in Wales' Black Mountains, the Green Man Festival returns for its eighth year. A family-friendly vibe and an eclectic line-up – plus the only 24-hour drinks licence of any UK festival – means that Green Man has a staunch following and a particularly welcoming atmosphere.

If you heard BBC's debut and shrugged, you were right to do so.

The festival season is upon us. But there's plenty besides dancing in a field to get excited about this summer: a new Mark Rylance spectacular, 'Toy Story 3', the return of Carlos Acosta, the National Gallery's forgeries...

Lured out of "retirement" by the American folk-harpist darling Joanna Newsom for a string of sell-out European dates, Roy Harper is no stranger to the admiration and respect of his fellow musicians. His collaborators and devotees read like a Who's Who of rock royalty and include Led Zeppelin (Jimmy Page is in the audience this evening), the Who, Pink Floyd, Peter Gabriel and Kate Bush. But Harper himself has a modesty and controlled anonymity that has kept him away from the mainstream music machine, and it is this staunch individualism that truly defines his work.

It seems the harp is having a moment. After Florence Welch brought 12 harpists to The Brits, American harp-playing folkie Joanna Newsom sold out the Royal Festival Hall for two nights and has received rave reviews for her enchanting album Have One on Me. It has taken a while for a British exponent to give the instrument a similar profile. Lancastrian solo artist Nancy Elizabeth uses the instrument in her beguiling work, but only the smaller Celtic version.

The medieval and futuristic rub up against one another on the fourth album from sisterly duo Sierra and Bianca Casady, whose eccentric folk-pop has become subtly familiar via advertising.
