Beginning next Thursday (and running through May 22), New York City (or at least a couple of its venues) belongs to twee thanks to the fifth installment of the NYC Popfest, which brings jangly bands from all over the world to wear their hearts on their sleeves and sell all their 7-inches. After a few weeks of being otherwise known as the band called "TBA," NYC royal-twee types The Pains of Being Pure at Heart have just been announced as the headliner for Thursday night's festival kickoff gig at Cake Shop. Fun! Also fun: An excuse to knock off work via a daytime show starring Tiger Trap/The Softies/Go Sailor standard-bearer Rose Melberg next Friday at the Paul Smith Sale Shop in Williamsburg. Full lineup (with links to buy tickets to the non-free shows and countries of origin for all the bands, in case you're feeling particularly patriotic toward one place) after the jump.
