Time for another single, this time from the London-based acoustic folk duo Copper Viper, which is Robin Joel Sangster (vocals and guitar) and Duncan Menzies (vocals, bouzouki and violin), except it isn’t this time because the duo’s a quartet for this release, and they sound very different. The two additional personnel are Issy Ferris (backing vocals) and Archie Sylvester (backing vocals, drums, bass and electric guitar). That’s Ferris and Sylvester, of course, known for their dynamic live performances and Archie’s also the producer for this single.

So this is Copper Viper, Jim, but not as we know it. “Opal and the Bear” opens with an atmospheric, Ennio Morricone-tinged intro, leading in to a first verse that could almost be Copper Viper au naturelle. The first chorus gradually builds to a second verse with the full band and a second chorus with the addition of electric guitar as well. There’s an acoustic solo that’s part Morricone/part Django Rheinhardt before a breakdown into an almost a cappella chorus and a final build-up before an acoustic guitar outro.

This single is dynamic and anthemic and it’s a perfect example of a seemingly unlikely collaboration creating a truly original piece of work.

“Opal and the Bear” is released on Friday January 29th on Under the Bower Records to download and stream.
