The Infamous Stringdusters will celebrate Halloween weekend this year with a two-night at the Fillmore Auditorium in Denver, CO, with several special guest artists in support.

The event, dubbed Big Top Halloween, will feature the Funky Meters and The Magic Beans on October 28 and Keller Williams’ Grateful Grass and The Lil’ Smokies on October 29. The Stringdusters will serve as Williams’ backing band for a portion of his Grateful Grass set.

Fan pre-sale for the run begins today, with general ticket sales starting this Friday, July 15. The Stringdusters will play the Northwest String Summit in North Plains, OR, later this week.
