The cape, the banked-up synths and the glam have gone. Rick Wakeman’s Grumpy Old Christmas Show consists of just the man, his piano and his stories and jokes, mostly about Christmas and family.

For a band mostly known as a brilliantly ludicrous cocktail of other’s people’s sound-styles, the Simulation Theory tour is proof that Muse have become musical legends in their own right.

“Thanks for being in here with us tonight,” Wayne Coyne begins, “when you could be outside with the universe shining down on us.” Having clearly experienced a pre-gig epiphany from the unexceptional South London sky, The Flaming Lips singer seems primed to take us all higher. And so this 20th-anniversary celebration of their breakthrough LP The Soft Bulletin begins with an explosion of joy.

Among the summer gigs being held in Caerphilly this summer, it seemed a tall order for electronic/math rock instrumentalists Public Service Broadcasting to pack out a castle. They may be more current, but the others (The Stranglers, Groove Armada, The Zutons et al) at least had notable commercial periods. PSB’s biggest singles have never troubled the UK Top 75.

Oh Sees have long been touted of as the perfect festival band. Their racuous, high-tempo rock'n'roll always riles up the drunken swathes, even if no-one recognises the song. However, going to a headline show is a different prospect - these swathes are the loyalists, not ready to accept anything less than carnage. After witnessing a relentless sold out show in Cardiff, maybe it's time to remove "festival" from that opening statement.

Now going for over a dozen years, ever-busier since Live Nation took over its parent company in 2015, The Great Escape Festival is the annual multi-venue band showcase and music conference which sees Brighton swamped with music biz sorts.

It was in the early 2000s in a tiny, gritty bar that I first saw Rodrigo y Gabriela live. Camden was less pretty then – a look was close to a glare and there were more spikes and kohl – the nineties were that much closer. I was right at the front, pressed up against a rib-height stage, alarmingly close to the percussive thrum taking place inches above my head. The atmosphere was heady, their acoustic performance electric. Their hands moved like fire, catching the area’s thrash sensibility – I’d not heard anything like it.

Their music is a bit wizard-y. It’s certainly imbued with a pungent sense of mammoth weed. And the “bastard” is surely for the sheer, meaty rock’n’roll heft of the word (much as Motörhead used it to title an album). But don’t be fooled. Mammoth Weed Wizard Bastard are not a passing indie-punk turn with a novelty name in the vein of, say, Ned’s Atomic Dustbin or Natalie Portman’s Shaved Head. Their new album carries serious weight. It’s heavy as osmium.
