And the pair's new album Two simply gets better with every listen.

Williams is already a big star in folk country with a Mercury Prize nomination for Little Black Numbers behind her along with an even better album four years later, 2005's cracking Over Fly Over.

Like her namesake Lucinda, Williams possesses shed-loads of grit and guile - there's nothing wishy washy about her largely down-to-earth roots country.

Two years ago she guested on the equally mega-talented Thea Glimore's Harpo's Ghost album: now she's teamed up with Neill MacColl - from the musical dynasty that spawned father Ewan, mother Peggy Seegers and sister Kirsty.

Unsurprisingly, their new album Two is an outstanding collection of songs that are generally sedate with the minimal use of instrumentation.

The quirky Grey Goes is among the many highlights.

Each song boasts fragile harmonising ? not heard since Teenage Fan Club's Grand Prix album!

Indeed, the heartfelt vulnerability of the sparring vocals is a reminder of the great Gram Parsons' legendary duets with Emmylou Harris.

In the track Weather Forever, the Williams/MacColl double act has produced a slice of new folk genius.

Elsewhere, the album boasts the dreamy Come With Me and the gorgeous finale, Holes In Your Life.

Two is very much a thing of astonishing beauty. Let's hope that commercial sales will encourage a quick follow-up.
