BBC Introducing: Winter Mountain Band
They hail from Cornwall and Donegal.
Indvidually they are Joe Francis and Marty Smyth. Individually they were already respected songwriters.
Together they have formed the Winter Mountain Band, peforming melodic folk songs, with a modern edge, but a hat well and truly tipped towards the great music era of the 1950s and 1960s.
Joe and Marty share song-writing duties, and their harmonies on the songs.
The duo popped in to BBC Radio Cornwall, to peform an acoustic set on the David White Show. Click on the audio link to hear the performance.
When you hear their music, it will come as no surprise who influences the musicians; The Everly Brothers, Lennon and McCartney, Lieber and Stoller, David and Bacharach, and Crosby Stills and Nash are among the many.
The duo met, by chance, on a train, in Chicago.
It proved to be a life-changing train journey as the two new friends revealed they shared similar musical passions. So began the Winter Mountain Band.
Joe said: "We jammed through some Crosby Stills and Nash stuff and Simon Garfunkel stuff.
"That was cool as it was the first time we'd both had the chance to play that music live with someone else. We're both fans of that music.
"Essentially you need two lead singers to pull it off and our voices seemed to blend."
At the end of last year Joe and Marty performed alongside Nashville singer/songwriter Sarah Watkins on her debut solo tour of the UK.
