The high pedestrian traffic makes Harvard Square a gathering place for street musicians and buskers, who must obtain a permit from the Cambridge Arts Council. Singer-songwriter Tracy Chapman, who attended nearby Tufts University, is known to have played here during her college years. Amanda Palmer, of The Dresden Dolls, regularly performed here as a "living statue". Another frequent performer over the years has been indie rock guitarist Mary Lou Lord. A small bronze statue of "Doo Doo" (a puppet created by Igor Fokin) sits at the corner of Brattle and Eliot streets, in honor of Fokin and all the street performers. The Flying Karamazov Brothers also performed regularly in Brattle Square.
