Disco Biscuits/Conspirator keyboardist Aron Magner sat in with Damn Right! at Philadelphia’s Underground Arts last night. Magner, who has performed with the group a handful of times in the past, emerged for the Damn Right! originals “Synth 2,” “The City” and “Summer in the 80s.” The latter song appears on the group’s new EP.

Damn Right! will perform at New York’s Brooklyn Bowl with Future Rock this evening. Conspirator will headline at Hurricane Sandy relief benefit at New York’s Club 39 on Wednesday.
