So, the first day's done. We awake, bleary-eyed and emerge from our tents and survey the scene. No matter how bad it looks for our immediate future health, the clouds are sure to clear before the inaugural beer and opening bands. The quality continues as we run through the very best we've seen this year to create the best bespoke festival we can imagine given theartsdesk's collective gig-going this year. In short, ladies and gentlemen… welcome to Sunday's line up of theartsfest 2015.

MAIN STAGE

Madonna 10.00 - 11.30

The festival market is one that has, like much of Britain, become oversaturated of late. Here at theartsdesk however, we feel that there’s room for one more as long as it’s of the highest possible quality. Here, then, is our line-up, a dream festival pulled together from our writers’ highlights of the past year. It’s two days over two stages and, best of all absolutely no danger of getting some hideous water-borne disease while sleeping in a substandard tent. 

As you all know by now, Friday is D-Day for Adele's new album 25, and part of the all-media Adelathon is Friday night's show on BBC One, Adele at the BBC. It's a mix of live performances and taped sequences linked together by chunks of interview with Graham Norton, and makes the perfect relaunch package for the reclusive superstar. It opens, aptly enough, with her performing "Rolling in the Deep".

The attack is relentless. Its power pummels like a gale. The 2015 model Mercury Rev begin their set at Iceland Airwaves as they meant to finish. Never has this band been so forceful, so kinetic. Yet their trademark balance of filmic drama and delicate melody was not sacrificed during this convincing revitalisation. On stage at Reykjavík’s Harpa concert hall on the festival's second day, Mercury Rev set a bar so high it sowed seeds suggesting nothing could top this. If they are playing, see them.

For an art form that has been quite often written off over the last half century, Jazz seems in extraordinarily rude health. Today sees the opening of the biggest ever EFG London Jazz Festival featuring scores of venues and hundreds of groups throughout the capital.

Allen Toussaint, who died last night aged 77, apparently just minutes after coming off stage in Madrid, was the soul of New Orleans. Irma Thomas, The Neville Brothers, Dr Longhair, The Meters, and of course the Nighttripper himself Dr John: all of them benefitted from his magic touch, whether as producer, arranger, songwriter or pianist of enormous talent.

We  had an awesome producer, Jerry Finn, who was just a few years older than us. Jerry was usually wearing a Replacements T-shirt and Vans sneakers. He had worked with Green Day, Jawbreaker, and a bunch of bands on Epitaph Records, including Rancid and Pennywise. Jerry wasn’t some asshole rolling up to the studio in a Bentley - he was one of us. He could be honest with us, and we would listen to him, which is really important.

Sometimes appearances can be deceptive. The frontman on stage looks as generic it gets. His scruffy beard, retro specs, baseball hat, shapeless jeans and the bulging outline of a mobile phone stuffed in his trouser pocket don’t add up to suggest that his band Tahiti Boy & the Palmtree Family are going to be anything distinctive. But the studied casualness belies what actually takes place musically. This is exceptional.

Can you have too much of a good thing? I ponder this as I scroll through the 109 watermarked MP3s of Bob Dylan’s recording sessions spanning 13 January 1965 to 16 February 1966, for Bringing It All Back Home, Highway 61 Revisited, and Blonde on Blonde.

An encounter with Hamburg’s Reeperbahn is akin to assimilation into a real-life kaleidoscope where bright lights, mass revellers and shills touting bars, night clubs or strip joints combine in a single multi-sense overload. The tumultuous thoroughfare is dedicated to excess.
