From the vintage black tie dress code to the converted schoolhouse acting as tonight's venue, it's clear from the off that Laura Marling's Secret Cinema collaboration isn't going to be your average gig.

For starters, tonight's gig comes with rules. Guests must adhere to the vintage black tie dress code, they must bring a host of unusual items for the Lady of the Manor, and they must sacrifice their phones at the door. The Old Cardinal Pole School has been transformed into the Grand Eagle Hotel, where butlers await your arrival and excited, giggling maids run around in pairs. There's a drawing room, where guests are provided with pencils and ink to create self-portraits; a writing room, stacked to the ceiling with old books and a table of typewriters; and a number of bedrooms - each complete with obscure Laura Marling references and old clothes, donated by the guests.

Unlike most Secret Cinema events, tonight's events don't follow a particular storyline. The maids and porters have secrets to tell if you're willing to listen, but they don't seem to allude to much and just end up confusing guests. A surprise appearance from Laura at the top of a balcony, to play a Bruce Springsteen cover, doesn't help matters.

With the performance now into its second week, the theatrics run smoothly, and a commotion breaks out in the lobby about fifteen minutes after Laura disappears. A scene plays out between a scary looking barefoot girl and her lover, and all the staff and guests gather to watch them dance and fight in tandem. At the sudden sound of a klaxon, the actors and actresses manage to gently shuffle the audience through the main hall and downstairs, when the guests start to run. After all the extravagance and drama of the evening, it's finally time for Laura's set.

The gig takes place in a schoolhouse round the back of the hotel, a comparatively plain and unsuspecting setting. Opening with the four-song medley from Once I Was An Eagle, Laura seems instantly at ease, and plays through the new songs smoothly and confidently. That doesn't last long, though. Laura's notorious for forgetting lyrics mid-song, and tonight's gig is definitely no exception. During third album track 'Sophia', she trails off halfway through, muttering 'Oh my god…' and looking to the crowd to refresh her memory. Her embarrassment is endearing, and nobody in the audience seems to mind. "The professionalism of this evening really highlights my lack thereof" she laughs.

Tonight's set is comprised mainly of songs from latest album Once I Was An Eagle, and Laura plays through them delicately and seamlessly. With the exception of a fast-and-furious rendition of 'Master Hunter', Laura plays through the album's more sombre moments 'Little Bird' and 'Where Can I Go' with quiet concentration. Before leaving the stage, she manages to squeeze in 'Night After Night' from her third album, and 'Rambling Man' from her second. After the earlier theatrics and drama of the evening, Laura's set felt like something of an afterthought. Whilst she played beautifully and the new album tracks sounded her strongest yet, the Secret Cinema group could have done better to include her more in the earlier activities, and give guests more of what they really came to see.
