MilkBoy Philly plays host to a packed lineup of fine local musicians assembled to celebrate Market East’s second release Children of Summer. The retrofitted trio specializes in creating smooth, tightly layered, tri-fold vocal harmonies that play off minimal instrumentation – perfect for making the ladies swoon. To help Market East celebrate this special occasion, they’ll be joined by Joe Sweeney & the Long Hair Arkestra, the latest incarnation of Mr. Philebrity’s nod to 70’s indie rock, the synth-y, sexual grooves of Night Panther, who are returning from their recent visit to Daytrotter, the touching intimate folk of Former Belle, and the emotive, inspiring, cinematic soundscapes of Mohican. This diverse lineup promises to touch your ears with a memorable tirade of talent. Milkboy Philly, 1100 Chestnut St., 9pm, $10 – $12, 21+ – Michael Colavita
