You may not have heard of Yellow Ostrich yet, but the New York trio—originally the one-man recording project of singer-guitarist Alex Schaaf—will be blowing up your playlist soon enough. The band—which now features former Beirut utility player Jon Natchez—will re-release its previously download-and-vinyl-only full-length The Mistress via Barsuk Records in August. For Undercover: Summer Break, the band tackled “In The Summertime,” which was a massive, massive hit for a British band called Mungo Jerry in 1970. The special location for this taping: the gorgeous Navy Pier deck outside Chicago Public Radio station WBEZ, home to such fine shows at Eight Forty-Eight and Sound Opinions. Thanks to S.O. producer Jason Saldhana for location scouting.
