Electric Six @ The Liquid Room, Edinburgh, 30 Nov

As Electric Six take to the stage of a sold out, cramped and claustrophobic Liquid Room in Edinburgh, you’d be forgiven for thinking you'd accidentally walked into a sales pitch for some shady multi-level marketing system. The members of the band are various levels of dishevelled, decked out in blazers (some of which are rather ill-fitting), chinos and the occasional askew tie. Lead singer Dick Valentine has the nervous energy of a stand-up comedian whose act is teetering on the edge of total collapse. It’s hard to tell how the night is going to go. Then the music starts.

Electric Six have been practising their brand of eccentric disco rock’n’roll since 1996 (with an ever-changing lineup) and it's instantly and clearly obvious that they are a well-oiled machine. Opening track Turquoise gets the packed-out venue moving and dancing, and the vast majority in the audience don’t stop until the band depart the stage at the end of the night. Even the mid-song banter is efficient and to the point, with a 20-second commentary about "pumping gas in the Dunferm-line region of Scotland" etching wide smiles on the faces of the crowd.

Tonight’s gig is split into two sets, the first featuring tracks from their latest release, Turqouise, as well as some of their hits and deeper cuts. The second set celebrates the 20th anniversary of their seminal debut album, Fire, with the record being played in its entirety.

There are songs taken from all over the Detroit rockers' considerable discography (their most recent release is their 15th studio album) peppered throughout the setlist, with highlights of the first half undoubtedly being the imperious Dance Epidemic and funk-rock anthem I Buy the Drugs. There is a truly joyous atmosphere in The Liquid Room, and when Valentine and co. step offstage for a quick break in-between sets, it’s clear they’ve made quite the impression on the audience.

As they emerge for the second set, with the frontman having applied a liberal layer of gel to his now shiny slacked back hair, everyone is ready to celebrate 20 years of the album that made the band mainstays on the likes of Kerrang! and Scuzz TV. Dance Commander sets the tone for the rest of the evening, with Electric Six seeming to step it up a level to celebrate the album that catapulted them to stardom in the early noughties, and the crowd respond in kind. The band are unable to hide broad smiles as they see in real-time how much people love their music.

Danger! High Voltage and Gay Bar are the inevitable standout tracks of the night, and it's almost deafening in the tiny venue when the first chords of each song ring out. Electric Six know exactly what the people want, and they do not hesitate to give it to them. They want fire in the disco, and fire in the Taco Bell, and that’s what they get. It's glorious.

The brief encore that follows allows them to say farewell to a city that clearly holds them dear in their hearts. The 30th anniversary should be even more spectacular.
