From a pure vocal standpoint, this may be the best How to Succeed recording I've ever heard. Obviously I can't say anything for Jonas' performance, but this EP is definitely worth a download and listen. I think he puts a really interesting spin on the songs, especially "How to Succeed," sort of jazz-ing it up a little bit.
So my charge to you. Download it. Ignore Nick Jonas' name. Judge. Then realize it's Nick Jonas and you will have a lot more respect for him.
UPDATE: In other H2$ news, they just announced today that the show will be closing on May 20th.
