American Idol star Adam Lambert continues to thrill crowds around the country on the American Idol tour.

Critic reviews describe Lambert as the standout of the tour, far above winner Kris Allen.

But you don't have to go the Idol tour live to see Lambert and the rest of the American Idol stars. Several new Lambert performances, both post- and pre-Idol, have emerged on YouTube in recent days and weeks.

Lambert delivers a stunning performance (see minute two) of "What's Up," the 4 Non Blondes '90s classic. Performed in a Los Angeles nightclub in front of what appears to be about 50 people, it's remarkable to see Lambert sing the feminist anthem with the same vigor and brilliance that he performed with on the American Idol stage, in front of thousands.

Also on the web is his Portland performance of "Starlight," by Muse.
