Happy May Day! Enjoy the first of the month with some live tunes. Here are some options:

Sia @ Canal Room: The angelic voice takes over the Chinatown venue this afternoon along with a handful of other singers. The show is brought to you for free by the Tribeca Film Festival, but requires badges for entry.

Robyn @ Virgin Megastores: The Swedish pop princess's oversea hit album finally hits American shelves today. She'll be stopping by the Union Square store to promote her release with some live love.

The Kills @ Webster Hall: Last time I saw this 'too cool for school' duo, I couldn't stop focusing on how smooth their hair looked. Props to anyone who can tell me what kind of shampoo they use.

I'm From Barcelona @ Brooklyn Masonic Temple: With 29 band members playing on one make-shift stage, this promises to be a spectacle.

Men, Women and Children @ Hiro Ballroom: GBH presents another hipsters-via-Chelsea dance party, complete with a load of DJs and some great electro rock bands. RSVP to ny@metromix.com for free entry.
