From the press release

Dr Pepper, MTV, and Epic recording artist Cartel are giving music fans more of what they want this summer … a first-time, real-time look into the making of the band’s newest album during Dr Pepper Band in a Bubble. In what is sure to be the most talked-about music event of the year, Cartel will be sealed inside a huge transparent bubble on Hudson River Park’s Pier 54 in New York City from May 24 through June 12, and every move they make will be live for the world to see as they eat, breathe, sleep and record the follow-up to their breakthrough debut album, CHROMA.

Pier 54 is located on the Hudson River at 13th St. Check out the satellite view from Google Maps here. I passed by the pier when they were still building the bubble and aside from official events it doesn’t look like you would be able to walk up to it and peek inside. The pier is quite long, the entrance is guarded and the bubble is at the end. It’s an odd structure that looks fairly small… I don’t know how they’re going to live in there for 20 days.
