It is hard to describe the Bill McGoldrick Acoustic Duo without inevitably invoking the “odd couple” cliché.

McGoldrick is a 57-year-old ex-rocker who spent the past few decades touring with a variety of bands before deciding he was ready for a different kind of arena; the other half of the duo is Pamela Stiebler, a 23-year-old folk singer and budding songwriter who as a teen was a backup singer for bands in her native Brazil.
