Bored by the typical show-going experience, wherein artists play on (yawn) stages? Try the Is Upstairs series, which features experimental musicians performing inside a 20,000-gallon metal tank suspended above the audience (!), which tunes in via video feed. Godspeed to all on tonight's bill: Jason Sanford and Patrick Higgins—members of Neptune and Zs, respectively, and each performing solo here—and the duo of percussionist Eli Keszler and multi-instrumentalist Ashley Paul.
