Enticing, one-of-a-kind varietals of performance and visuals are Highwire Gallery’s stock in trade. This evening’s show, featuring the combo of Mary Lattimore & Jeff Zeigler and Fursaxa, is unique for several reasons. Not the least of them being that it’s an opportunity to see two of Philly’s most ubiquitous – and disparate – performers take on their own sets. Mary Lattimore, the city’s best known indie harpist, is releasing her first solo album The Withdrawing Room next month, after years of building a reputation providing filigreed, ethereal backing for such notable artists like Thurston Moore, Daughn Gibson, Kurt Vile, Meg Baird, Nightlands, and many others. She’ll be joined on stage by Jeff Zeigler, who (in addition to his recognizable stature in Arc in Round) produced her record at his studio Uniform Recording. He also has his own solo sound plus a gift for collaborating with Lattimore on some mind-bending synth-harp work. These two will be sharing the bill tonight with Fursaxa, a project born of Tara Burke’s avant-garde roots and a fondness for the Philly experimental scene – her collaborators include Helena Espvall and Bardo Pond.
