Even if their last album, Congratulations, was a major disappointment for most of us, it didn’t stop MGMT to perform a full fledge concert at the Ed Sullivan Theatre after recording a performance for the David Letterman Late Night earlier that day.

By the way, if you are unable to watch the video, well it seems that only United States residents can watch the video so far… I don’t know if it will be ever released internationally, but for now, that’s all we’ve got. I can’t even watch the video myself, being from Canada sooooo yeah, it’s all about the readers right? ahah.

It’s actually hard to find a follow up to a major release like Drop The World of Lil Wayne, but you can’t get enough of Alicia Keys, I mean come on … Anyway, she was on Late Night with David Letterman to promote her newest album The Element of Freedom with her latest single Try Sleeping With A Broken Heart.

Alicia Keys newest album, The Element of Freedom can be found in retail stores and on iTunes as of now.

Florence Welch made her United States television debut on David Letterman performing the first single she released in the UK, Kiss With a Fist, which is a bit odd, as the song is very different from the rest of her album as it’s mainly sound alot more indie/punk-rock than everything else she released on Lungs and that reminisces the sound she and her band had when they first started.

On a related note, Florence + The Machine is in town this sunday with Hey Rosetta! at le Cabaret Juste Pour Rire. I’m not sure if there’s any tickets left, but you’ll be totally miss out if you’re not attending this show.

Canadian artist Feist joins Wilco on David Letterman where they performed the song You and I featured on Wilco’s latest album entitled Wilco (The Album)

After seeing them live on tuesday, I have to say that Phoenix was probably one of the best act I’ve ever seen on stage … and I’ve seen alot. Here’s a video of them performing 1901 on David Letterman.

ps. the singer is totally wearing the same outfit he was on tuesday too lol.
