NOVEMBER 19

Like black-powder Civil War buffs refusing to charge their weapons with modern explosives, some players of traditional music eschew material or instruments uncertified as dating to Way Back When. Not so the Battlefield Band, a Scots outfit happy to mix synthesizers and bagpipes and all points between if it gets the song over. The Battlefielders move forward into the past Friday at 8 p.m. at the Barns of Wolf Trap, 1624 Trap Rd., Vienna. $12. (703) 938-2404. (Michael Dolan)
