Adam Lambert + Orianthi + Allison Iraheta

Adam Lambert, American Idol star and gleefully out gay icon, brings his Glam Nation tour to town for two nights. Expect high theatrics to accompany Lambert's crisp, impressively hooky pop tunes. Sharing the stage are Aussie singer-guitarist Orianthi, best known as the intended lead guitarist for Michael Jackson's This Is It shows, and talented Idol season eight also-ran Allison Iraheta.
