  Top four performed rock songs last night with the help of Slash, and tonight we find out who will go home. It's just a matter of sitting back and waiting an hour to find out, but really, do we need a whole hour? Apparently, according to the Idol producers, we do. Although, tonight, I may agree. No Doubt and Chris Daughtry will be performing tonight. That is a lineup I can get behind. Breaking again from tradition, the group performance is also featuring the mentor from last night, Slash. The guy has not lost a thing in his playing. In my eyes, Slash revolutionized the guitar solo, and tonight, he showed us how.
