Tiny Masters of Today isn’t so much a cute name for a punk rock band as it is an accurate description of an honest phenomenon. In late 2005, tiny 13-year-old Brooklynite Ivan (then 11) and his tinier 11-year-old little sister Ada (then 9) reached across the playground and started a punk band. Both play guitar and drums. Ivan plays bass and Ada plays keys. New video and more after the jump.

The kids released a few EPs, caught some scenester love, and found themselves in the studio with Yeah Yeah Yeahs, CSS and Liars. They released their awesomely-titled debut Bang Bang Boom Cake in August last year and the music is as enjoyable as you’d expect and considerably more, well, punk. Check out TMOT at SXSW before E! True Hollywood Story reveals how parents and managers ruined it all. New video for “Hologram World” featuring Karen O and Nick Zinner of Yeah Yeah Yeahs is below.
