Just found this one. Scottish folk band "Back of the Moon" will be at One Longfellow Square in Portland, ME Thursday 11/8.http://www.onelongfellowsquare.com/
One of Scotland's finest Tradional music bands, 2005 saw them win 'Best Folk Band' at the Scottish Trad Music Awards, while their brilliant new album 'Luminosity' was nominated for 'Best Album'.

Back of the Moon are a traditional Scottish folk band, with both new and traditional tunes and songs cast in fresh modern sounding arrangements. Since forming in 2000, the band have rapidly gained a reputation for their dynamic live performances, touring annually throughout the UK, Canada, USA and eight different European Countries. Back of the Moon create their giant acoustic sound through a tightly woven frontline of Scottish border pipes and fiddle, an intimate pairing of low whistle and flute, the distinctive rhythmic force of their guitar/piano rhythm combo, at times augmented by bodhran and Cape Breton Stepdancing, and awesome three-part vocal harmonies in their Scottish songs - in which each unique singer takes the lead. 2005 saw them win 'Best Folk Band' at the Scottish Trad Music Awards, having received "Best Up and Coming Act" at the awards back in 2003 and "Best Celtic Group" at Lorient Interceltic Festival 2003.
