SEVEN-piece pop collective Urvanovic launched the release of their debut album, Amateurs, with an enchanting performance at Glasgow’s13th Note on Tuesday.

The multi-talented band, which is generally composed of two vocalists, keyboards, drums, trumpet and a trio of string players, brought the small venue to life with their rich and affecting sound.

Originally set-up as a studio project by songwriter and music student Tom Irvine, Urvanovic are now evolving into one of the most eclectic sounding groups in the country.

“We formed in 2012 but the group has grown massively,” says Irvine, who plays keys and guitar as well as singing. “At first I was just mucking around on my laptop, but soon I wanted to add strings and it just began to build from there.”

“I never intended to start a live band or anything. I was originally just a student of composition on the popular music course at Edinburgh Napier University.”

Irvine is not alone; virtually every member of the band has studied music in some capacity. Where Irvine has learned composition, others are of a classical or a traditional folk background. Given the band’s assortment of musical credentials, these different elements come together in a majestic way when placed together.

“We’re very into the likes of Sufjan Stevens and Menomena,” says Irvine. “The instrumentation makes for a big sound, but we love naturally stepping it up anyway. A lot of our songs tend to build towards a big finish.”

Tuesday’s show presented a band that appeared in their natural environment despite the limitations of a small stage, with only just enough space for the cellist and two violinists.

However, vocalist/trumpet player Seonaid Stevenson stresses that this was unusual: “At our last show in Edinburgh, we had brass and woodwind players on top of our core members, so overall there were seventeen performers on stage.

“It’s a difficult dynamic to maintain – it’s hard enough to even get the seven of us to rehearsals at the same time – but we always have someone who can step in for different shows.”

Irvine echoes this, declaring that the band are “over prepared for everything”.

“Every single live show we do is probably different in some way. We have different versions of our songs, just in case, but everybody knows them inside out. There’s a real camaraderie to what we do, and that’s not changed as new members have joined.”

This communal feel was manifest throughout Tuesday night, and this was evidenced by the performances of two arguably more recognised acts during the support slots. Finn Le Marinel, of math-rockers Trapped in Kansas, kicked off the night with fragile vocals and intricate guitar.

Accompanied by minimalist percussion and keys, established songwriter Panda Su followed, performing tracks from her forthcoming album that sounded even more beguiling than her previous material.

The intimate feel of these sets only further highlighted the size of Urvanovic’s task.

In spite of their time being cut by curfew, the make-shift septet delivered a remarkable type of mini-spectacle.

The harmonies and gang vocals of recent single Open Ground were impassioned, backed by stirring instrumentation that elegantly dipped in and out depending on mood.

Tracks like Waterworks also demonstrated the band’s mettle when it comes to adventurous songwriting, working in syncopations and different time signatures without sounding forced.

“Our favourite songs are definitely the weird ones,” explains keys and laptop operator Niall Sinclair.

Nevertheless, the most impressive component of all was the band’s clear aptitude for crafting big pop songs that tug on the heartstrings.

“Whether the band choose to instrumentally expand any further or not, you can be assured that their current approach is most definitely working.”

Amateurs is released on Monday on Survivalist Records.
