Monday night, the five nights of SPIN's massive anniversary celebration, SPIN 25 with ZYNC from American Express, kicked off with a bang! Following the Smashing Pumpkins performance at Terminal 5, V.I.P guests were granted entrance to an afterparty held at the Hudson Bar, featuring a DJ set from Apache Beat frontwoman IIirjana Alushaj, and complimentary Amstel Light and Vitaminwater for the partiers.
