Queen + Adam Lambert preview their summer tour on iHeartRadio (VIDEO)

Adam Lambert and Queen previewed their summer tour on iHeartRadio on Monday.

And so Adam Lambert's transformation into a replacement lead singer for a rock band has started.

This was too anemic a performance for me. Where's the rock? Where's the energy?

Granted the surviving members of Queen are in their sixties already and may not have the same energy as before (Brian May is 66 and Roger Taylor is 64), but Adam Lambert is just 32! Why is he singing like a jaded singer already?

Queen is but a shadow of their old selves now. How sad.

I had high hopes that Adam would energize this band since he's such an amazing vocalist. Perhaps they just don't have the chemistry because of the age difference.

This may not be the career comeback Adam was looking for in the entertainment industry. He needs a big comeback so badly after his American Idol days. This looked good on paper.
