Made my morning. An explanation. From NYC Blog:
"After finishing up a gig last month, musician Derek Beres of the band EarthRise SoundSystem stopped into Punjabi Grocery & Deli at 114 1st St between 1st Ave and Ave A. 'The saag is spiced perfectly, the gulab jamun not too sweet,' Beres explained, "and vocals ring out non-stop through the night.'
"He ordered his food and stood at the counter ready to eat, tapping out a beat. What followed was an amazing impromptu performance of Bhangra."
