The Theme
Rock Music, which was appropriate for 1/2 the finalists and a chore for the other 1/2. Naturally those who fit the glove more perfectly were given high (or highish) praise. Those not, were given unceremonious flack or excuses. Their mentor was Slash, who looked completely out of his depth.

Voted Off:
Allison Iraheta, who sang her heart out during "Cry Baby," but got little more than lukewarm reviews from the judges, mostly about the song choice. Kara and Randy agreed "Piece of My Heart" (which has been done to death in the audition phases) was a better song choice. Admittedly, the song didn't show off much range. She managed to outdo Adam Lambert during their duet, "Slow Ride" which was misguided from note 1. She showed again she has stage presence, even though it looked like a brother and sister metal duo from the 80s rocking out in a stage that happens to be in their basement.

"Piece of My Heart": B
"Slow RIde" (w/ Adam Lambert): C

Should've Gone Home:
Danny Gokey, who massacred "Dream On" and still had the nerve to smile smugly. His final note was awful. It doesn't help that Gokey is the new pick for Vote For the Worst, the anti-Idol community. They don't get points for originality (they call Gokey a douche) but they are at least accurate.

It's worth mentioning VFTW has also supported Matt, Lil, Scott, and Megan until they all eventually dropped out (some the same week as their support).

Gokey didn't add much to his duet with Kris Allen, "Renegade," but got marks from Simon Cowell for being "better. The judges accepted the sludge, though, saying that it wasn't his type of music but he gets points for trying.

"Dream On": D-
"Renegade" (w/ Kris Allen): C

How Was Everyone Else?
Kris did a quite capable version of "Come Together" that was clearly more Jason Mraz than Steven Tyler, but it came off as genuine and laid-back. Simon accurately referred to it as a jam, but he didn't mean that quite so complimentary. Adam raged through Zepelin's "Whole Lotta Love" with the confidence of an original artist and the judges promptly went down on him.

"Come Together": B
"Whole Lotta Love": B
