As a prelude to the lighting of the City of Williamsburg Christmas Tree, Timothy Seaman celebrates Virginia's rich diversity of trees that so festively adorn the holiday season, with interpretations of sundry tunes and songs such as 'The Holly and the Ivy,' 'O Tannenbaum,' and 'Down in Yon Forest,' featuring the hammered dulcimer, flutes, mountain dulcimer, and psalteries --- both traditional Christmas music and his own sparkling compositions on the theme from his CD Sycamore Rapids.
