A band’s music is available to everyone. But what goes on behind the scenes can change their reputation, for better or worse.“Wind and Willow,” or Mark Tillman and Sarah Peters are getting married this month, a fact that is hard not to see when they’re performing live. While boy/girl duos are nothing new, “Wind and Willow” has a story that’s pretty unique. Mark met Sarah while working in Canada, and since then they’ve been exchanging music and talking, a lot, on Skype. Divided by two countries, it’s only been within the past few months that Sarah could move to Raleigh. Since then the duo has been able to really develop a mature sound, with each member contributing a vital, but incomplete part without the other. Sarah’s powerful voice can give a song its intensity at times, and it’s sweetness in others. Mark’s impressive assortment of instruments gives each song it’s unique character that Mark exhibits himself, both on and offstage. Both"Wind and Willow" as well as Mark and Sarah, have a lot to look forward to, though it may be a while before we see them onstage again.
