Sudden Wells is a new group that stands at a crossroads between Gallen’s output as singer and songwriter with Dublin band Ana Gog and his work as a celebrated and widely-performed composer. Sudden Wells combines both worlds, weaving widescreen, cinematic contemporary soundscapes around Gallen’s evocative songwriting, all performed in the live setting by some of Ireland and Europe's finest contemporary musicians.

Róis body of work includes ensemble, large-scale and small-scale works, solo pieces, electronic solo/ensemble pieces and short film/multimedia works also. Her unique sound is an idiosyncratic combination of modernist and contemporary music with inflections of Irish traditional music, folk and Jazz.
