So, what happens when you get to The 100 Club just as the doors open for a private event on a Sunday evening? Well, the obvious answer is, not a lot, so plenty of time to check out how the stage set-up looks and work out the best photo angles for later. When that’s done, there are still only four people in the place, so what next? Right, ask the sound engineer about the programme for the night; apparently The Grahams (the band I’ve come to see) are going on at 9:30. Is there a support band, don’t know mate. Oh well, time for another bottle of lager then.

Then, out of nowhere, the door opens and what is unmistakably a bunch of musicians walks in; the instrument cases are always a giveaway. After about half an hour of intensive roadying and oneing and twoing, we have ignition. None of this leaving the stage and coming back to make an entrance; a quick line check on the vocal mics and its 1-2-3-4.

Surprisingly, after all the last minute preparation, The Orange Circus Band was pretty good, playing hillbilly Americana with a constantly changing instrumental line-up featuring bass, acoustic guitar, banjo, mandolin and fiddle and featuring a bit of the almost obligatory Woody Guthrie. They finished with the lovely four-part harmonies of the gospel song “I’ll Fly Away” and everyone was happy, but I can’t help wondering how much better they could have sounded, with a full-on soundcheck.

No such problems for The Grahams; they soundchecked before the venue opened and blasted straight into the set with “Griggstown” from the new album, “Glory Bound”. Although Doug and Alyssa Graham’s second album was released this week in the UK, this gig was about the short documentary, “Rattle the Hocks”, made at the same time, about the influence of the railways on the growth of Americana music, which is showing at Raindance Film Festival. Although the album versions of the songs feature full band arrangements, the songs are so good that they all work with two guitars, two voices and a bit of percussion. The set featured mainly material from “Glory Bound” including “Kansas City”, the folky and personal “Blow Wind Blow”, the album’s closing song, “The Promised Land”, “Tender Annabelle” from the bonus tracks and the double entendre-laden “Biscuits”. All of those were delivered with style and panache, but there were also a few very special moments.

About halfway through the set, the first highlight was the gospel-tinged and deeply personal “Mama”, which was the first really emotional moment, followed fairly quickly by “The Wild One”, which is a standout track from the album. It’s a tragic coming-of-age story with a huge uplifting chorus and it’s a single if I ever heard one. It’s gorgeous. “Lay Me Down” was another album high point which translated perfectly to a more stripped-down format and had Alyssa shifting from her pure and clear country tones to something much more like Alanis Morissette or eighties Marianne Faithfull. Which just left “Glory Bound”, inspired by Woody Guthrie’s “The Farmer-Labor Train” as the unplugged encore and a final lovely moment.

Seeing The Grahams live was quite an experience. Doug and Alyssa built a warm rapport with the audience by talking about the film, the album and their relationship, emphasised by their obvious onstage chemistry. The songs are intensely personal and are delivered with passion, power and beautiful harmonies; by the end of a gig, you’ll feel elated but wrung-out. If you missed this one you can catch them on their UK tour in November.
