Golden Sound Records has organized what’s looking to be the best party of this month’s First Friday activities. The local label is blocking off 19th Street between Baltimore and Wyandotte and has invited acts from its roster (Fullbloods, Empty Spaces, Everyday/Everynight) and a few others, such as Ghosty and Soft Reeds, to perform. Also on hand: food-truck action from the Magical Meatball Tour, the Good You and others. The festivities begin around 4 p.m. and run until 11 p.m., at which point the party moves to the Bulldog. See crossroadsblockparty.com for the full lineup and schedule.
