Steve Earle is country music's great polymath - short story writer, playwright, novelist, activist, actor, oh yes, and singer and songwriter of some of the most acutely intelligent and literate songs in contemporary country. He's adept at evoking the human cost of American history, American politics and the lay of the promised land, and on his latest album, The Low Highway, the first song takes a long, slow panning shot of the body politic. It’s not in great condition. Happily, though, Steve Earle’s muse is.

Imagine the rising and falling piano cadences of Gershwin’s Rhapsody in Blue. Then plug the gaps between each note with any of those which may have been encountered on the path to the next. Once that’s done, ensure that the playing is constant with each note bleeding into the next. Mesh the result with a similar composition played at the same time and you have some idea of how Lubomyr Melnyk’s “Windmills”, his final piece last night, sounds.

Scott Walker: The Collection 1967-1970

Jamie Cullum's sixth studio album is about as good a pop record as you'll hear all year. Newly signed to Island Records, the singer-songwriter has seemingly raided ideas from the entire history of pop music, such that low-fi vintage synth lines and jazzy piano breaks rub shoulders with heart-on-sleeve soul belters and subtle electronica. The kind of stylistic pluralism that directly reflects Cullum's own musical loves, in other words.

From being “a strange facsimile of the original” to generating the “first British record made by people who are 100 per cent convinced that they are doing the right thing”, Rock ‘n’ Roll Britannia breezily mapped the protracted birth of a British rock scene which could take America on at its own game. As Cliff Richard put it, what was created was “different enough to become European. Or other-worldly.” It took The Beatles to crack America, but they would not have done so without being rookies in Britain’s Fifties’ musical boot camp.

The ICA was the perfect location for the UK debut of hotly tipped new duo Tomorrow’s World, consisting of Air’s Jean-Benoit Dunckel and English synth-rockers New Young Pony Club’s ivory tickler Lou Hayter. The venue added a prestigious edge to what promised to be an auspicious occasion. A scant crowd suggested this was more of a test run than a full-blown debut, but they needn’t have worried about the reaction. Their music spoke for itself.

For those familiar with Ginger Baker’s virtuosic musicianship, but not with his life, the biggest revelation of the warts-and-all documentary Beware of Mr Baker may be that next to drumming, playing polo was the great time-keeper’s obsession. One might expect a jet-setting country gent like Bryan Ferry to mount up for a chukka or two before teatime, but the wild man of Cream and Blind Faith, late of Lewisham? Does Topper Headon play bowls?

The final concert of The Jim Jones Revue’s four-night stand at Bethnal Green boozer The Sebright Arms found the box-like basement venue packed with men – and a few women – who would recall a time when watching short-haired rock bands in this type of space was the cutting edge of British music culture. These days going to see a rock band on a Saturday night is possibly as quaint as attending a scooter rally. But The Jim Jones Revue conjure up those halcyon days when leather jacket-wearing rockers communicated a primal excitement like little else.
