During his long career, Bob Dylan has marched against the Vietnam War, campaigned for the civil rights movement, and written progressive anthems which highlight such social blights as poverty, racism, criminality and nuclear proliferation.

Bob Dylan is facing some awkward questions after it emerged that several of the paintings in his latest art exhibition were copied from photographs that he found on the internet.

How many roads must a man walk down, before he... realises that he's seen this somewhere before? Bob Dylan is facing some awkward questions after it emerged that several of the paintings in his latest art exhibition were copied from photographs that he found on the internet.

Fierce Tears offers further proof that the oboe's contemporary repertoire continues to thrive; and in James Turnbull it has a worthy champion.

Bob Dylan's most revolutionary impact on songwriting was his personal presence in his work, autobiographical authenticity not discernible in, say, Cole Porter. British jazz singer Barb Jungr's performance tonight, accompanied by pianist Simon Wallace, is the strongest proof I've heard that his songbook will outlive him. Even if Dylan's records were melted down tomorrow, the restless vitality she finds in their content will survive.

Bob Dylan, Jack White and Norah Jones have recorded previously unreleased Hank Williams songs.

Twin Atlantic's "Free" is the impassioned sound of young Glasgow – fast, furious and repeatedly championed by Kerrang! magazine. The band have been around since 2007, playing festivals, getting sticky on YouTube, touring the US, and making the sort of baby pop metal that goes down well at uni. But until "Free" (the title track of their first proper album, two years on from the critically acclaimed mini-album Vivarium) they had yet to come up with a hook that might hint at immortality. As they use so much that has gone before them (their line-up, the genre, the form itself), these days groups like this – and it has to be said that there are many groups like this – find it difficult to get the traction they need.

A member of roots-music group Donna the Buffalo for 20 years, the fiddler/accordionist Tara Nevins chose former Dylan sideman Larry Campbell to produce her first solo outing in over a decade.

Barack Obama has never spoken of his fondness for the late Phil Ochs, and it is completely possible that he has never heard of him. One of America's foremost protest singers, he described himself as a "left social democrat", and during the Sixties became a staple at civil rights rallies, student sit-ins, and anti-Vietnam marches.

Seeking to expand his musical outlook beyond his purely gospel influences, "sacred steel" guitarist Robert Randolph hooked up with producer T-Bone Burnett, and found himself dropping $5,000 on iTunes in 18 months, catching up on things he'd never encountered (such as Chess Records).

If you see their jaunty pop promos – old-fashioned, so weirdly refreshing – or ever watch them live, County Down band Two Door Cinema Club (so named when guitarist Sam Halliday mispronounced the name of the local Bangor cinema, Tudor Cinema) sort of crouch down, curling over their instruments, as though they've possibly only just learnt to play them – carefully watching their fingers crawl up and down the fretboard, not entirely sure where they're going to end up. This is engaging, and makes them appear even younger than they are, the best boys in their class, beavering away under an imaginary glass ceiling, effervescent and jangly in equal measure. In preppy jumpers, plimsoles and sports jackets, with floppy fringes and smiles, they look not unlike Haircut 100, Orange Juice, or any other floppy-fringed boy band of the past 30 years.
