It has taken longer than expected for Glasgow alt rockers Verse Metrics to release some new music.

“If you’d told me it would have been four years before we released anything else I’d have burst out crying, but a lot of good stuff has come out of that,” says Bob Dick, the band’s singer.

“It’s just life. I got married and was working six days a week, our old drummer moved to Dundee and band practices were having to take place here there and everywhere. It wasn’t very coherent and it’s hard to write like that.

“We’d go two months without a practice and there was no momentum, and we had various line-up changes. When we got my friend Kevin (O’ Hagan) to fill in on bass and our old drummer was back in Glasgow for a bit then we started to get that momentum back. It was a long journey but we are where we want to be.”

Now the group’s revamped line-up – Bob, guitarist Al Conway, bassist Chris MacKinnon and drummer Calum MacVicar – will officially launch their lengthily titled EP, We’ll Be Listening and Remembering Until We’re Old And Unsteady, at the Old Hairdressers on Saturday night.

They will come to the EP launch fresh from a successful tour down south, while the foursome’s twisty-turny post-rock has already been compared to a host of acts, from long-running American outfit Appleseed Cast to the moody likes of Interpol.

It’s the fourth release by Verse Metrics, but Bob believes they have now found their own sound.

“Lyrically there’s a lot more with the new songs,” says Bob.

“I feel we’ve moved on from the previous EP. Me and Al wrote a lot of the lyrics together and he was much more of the wordsmith while I was all about the music and the melody. I was never that taken by lyrics unless they were stand out bad, but this time I paid a lot more attention to that, and move the band on that way.

“I wanted things that were a bit more personal to sing, that meant a bit more to me. A lot of people said the past record sounded like an instrumental record with vocals on it, whereas the new one sounds like more of a whole piece.”

The band will now showcase that on Saturday, their first Glasgow headline gig in years. They’ll be joined on the night by a trio of excellent supports they have handpicked, with Bear Arms, instrumental act Adult Fun and singer-songwriter Finn LeMarinel all on board.

“We did a support slot last September, I think, and before that the last Glasgow gig we did was a long time ago, so we’ve not overexposed ourselves over the past couple of years,” adds Bob.

“It’ll be nice to just get onstage and play – it’ll be nice to do a gig without driving 12 hours first, too, like we had to on the UK tour. I don’t really know too much about Adult Fun, but I caught them at a gig and they were really good, so thought we’d ask them to play. We’ve toured with Finn before and know him well, and Bear Arms are one of my favourite bands in the local scene, so I’m just looking forward to the whole night.”

Despite the lengthy gap between releases and membership changes, Bob wasn’t tempted to ever say farewell to the band.

“I never even once considered calling it a day,” concludes the singer.

“It’s a big part of who I am – the day I don’t enjoy it is when I’ll stop, but I still get that enjoyment and want to challenge myself with it. I don’t feel like I have maxed myself out and that I have still got more things to give with it.”
