Martin Leamon and Sille Ilves formed their unique Welsh–Estonian collaboration SILD (Estonian word for bridge) shortly after the 2001 Viljandi Folkmusic Festival.. Since then they have developed a truly original fusion of two different musical cultures, rooted in tradition yet thoroughly modern, creating timeless music.

Sille is one of the best fiddle players in Estonia. She is also the leading exponent of the Hiiu-kannel (bowed harp), and an astonishing singer. She has performed at festivals and concerts in throughout Scandinavia and Europe.

In Wales she has played with top Welsh traditional musicians including Ceri Rhys Matthews, Cass Meurig and the KilBride Brothers. Martin plays guitar and bouzouki with great skill and sensitivity.

He performed for five years with Welsh band Boys From The Hill, and has also accompanied leading Welsh singer Julie Murphy. With these and other projects he has played throughout the British Isles, Brittany, Portugal, the Czech Republic and Estonia.
