Sometimes you hear something new and your perspective on music shifts seismically, making everything you were listening to previously sound safe and predictable by comparison. Inevitably, as one gets older and more musically knowledgeable, such moments are fewer and further between; either the shock of the new isn’t as high-voltage as it used to be, or it just irritates rather than stimulates. And so it was a pleasant surprise when, one morning – heralded by a storm of tape hiss and an enthusiastically bashed tribal drum – a new band called tUnE-yArDs (aka Merrill Garbus) came at me from the hi-fi speakers like a Dadaist, feminist pop warrior.

It may have taken just three days to record, but this new duo recording from sax player Branford Marsalis and pianist Joey Calderazzo has 13 years of music-making behind it, dating back to when Calderazzo replaced the late, great Kenny Kirkland in the Branford Marsalis Quartet in 1998.

Be different - take a festival break in Europe instead of the UK, and catch a different landscape. While artists in both new music and classical are constantly circling the world in search of more picturesque settings, you can find your alternative Glasto in Denmark or Belgium, or you can find favourite chamber musicians in Austria rather than London. theartsdesk brings you listings of this year's major European festivals: rock in Sonar, Sziget and Stradbally, opera in Bayreuth, Verona and Salzburg, dance in Vienna, Epidauros and Spoleto, visual arts in Istanbul, Zurich and Avignon. This is the indispensable clickable guide to a cultured break in Europe.

The first night of this weekend residency by the renowned bassist, composer and band-leader Charlie Haden celebrated the 25th anniversary of Quartet West and their new Emarcy release, Sophisticated Ladies. A winning mix of tender balladeering and coruscating instrumentals, the quartet's music-making – rather like the finest wines – seems to improve and deepen with age. While all groups are capable of whipping up a barnstorming fortissimo, it's only the great ones that operate as well at the other end of the scale. And the Quartet West pianissimo is nonpareil.

It took until the fourth song of their set for Suuns to take off. Lurching into “PVC”, the Montréal quartet gelled. Monolithic drums, pounding, relentless bass guitar and slabs of sheet-metal guitar rolled off the stage. Harnessing the power of heavy metal, they’d achieved escape velocity. More powerful than on album, the unassuming-looking Suuns made a compelling case for their stripped-down, post-Krautrock rock.

America has been very good to Hugh Laurie. His starring role as Dr Gregory House has shot him to the top of the earnings tree in US television, while comprehensively demolishing existing preconceptions of him as the blissfully idiotic Bertie Wooster, or the half-witted Prince Regent in Blackadder the Third. You might even say that with House, Laurie finally got the chance to play Blackadder.

I've spent the last week feasting on John Martyn via Spotify. He was a gap in my musical education. He turns out, as a large portion of you reading already well know, to be a rich, raw talent. I knew his rep but had a misguided notion he was another blueprint for whiny contemporary singer-songwriters. All that reveals is my own ignorance.

This is, not to put too fine a point on it, a masterpiece – but it could easily have been a bloody mess.

Catalan dance is one of Sadler’s Wells’ themes this spring, though I’d love to know how much of what Tap Olé does can really be called Catalan - this is a tap fusion company that owes its germination to Riverdance, Tap Dogs and the efforts in New York recently to revive rhythm tap. Attaching tap class skills to Spanish guitar makes what’s on at the Peacock this week more a tap show in a tourist-trail tapas bar than a theatrical dance production worth a detour.

Hugh Laurie knows we're going to be doubtful. He knows that this is a vanity project by the most successful TV actor on the planet, the man who is House. He could have walked into Warner Brothers and said he wanted to do an album of auto-tuned Euro-disco with David Guetta and some middle-management toady would undoubtedly have hit the green light. Thankfully he didn't.
