According to Adrants:
For its album Dig Out Your Soul, international super-band Oasis gathered 15 street bands and taught them the lyrics and sheet music for four of its new songs.
Last week, the bands were then deployed all over the city — mostly to subways — to perform the music with their own flavor. Each performance featured a little sign that said, “You are the first to hear this new Oasis song” — bringing a little bit of magic to busy commuters, and some eclectic street charm to Oasis’s new oeuvre.

Great execution and idea. Kudos to BBH/New York.
