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.

It’s the season of giving so theartsdesk on Vinyl feels compelled to draw your attention to Unicef’s Blue Vinyl campaign. This sees 17 celebrated albums auctioned off in special editions on givergy.com with all proceeds going to Unicef’s Children's Emergency Relief Fund. Albums include classics by David Bowie, Kate Bush, Alicia Keys, Ozzie Osbourne, Jimi Hendrix and… The Spice Girls. Go and have a look.

Baxter Dury, Etienne de Crécy and Delilah Holliday - B.E.D. ★★★★★ A small but perfectly sleazy work of sweary, cynical brilliance

Implausible times call for implausible music, and it doesn't come much more unlikely than this. Hawkwind, the die-hard troupers of gnarly cosmic squatter drug-rock, have re-recorded highlights from their catalogue, arranged and produced by Mike Batt. Yes, Mike “Wombles” Batt. Mike “Elkie Brooks” Batt. Mike “Katie Melua” Batt. Mike “Bright Eyes” Batt.

Oh Sees have been perennial festival favourites for over 15 years now, releasing 21 albums under seven different band names. The change of name usually indicates a new direction, with previous records ranging from alt Americana (OCS) to lo-fi garage (Thee Oh Sees).

Concluding a trilogy of releases that began with the EPs Not the Actual Events (2016) and Add Violence (2017) – Bad Witch is being called an LP despite its six tracks clocking in at only 30 minutes, a discrepancy that reportedly led an exasperated Trent Reznor to sound out a pernickety fan in an online forum.
