The real competition begins Wednesday night on American Idol when the Top 13 contestants — a stronger, more dynamic batch than we’ve seen in a few seasons — take the stage. Here’s a rundown of the contestants that will sing for your votes:

1. Casey Abrams, 20 (Wilmette, Ill.)

An early front-runner thanks to his wildly invested performances, Casey skillfully yet effortlessly inhabits his songs in a way that none of the other Top 13 contestants have been able to do. I dig his jazzy vibe and impeccable vocals, and I’m eager to see if he’ll be able to shrug off the Taylor Hicks comparison over the coming weeks by proving his versatility as an artist.

2. Naima Adedapo, 26 (Milwaukee, Wis.)

The judges were right to throw Naima back into the mix as a wildcard, as she brings a certain character and spice to the Top 13 with her commanding, throwback voice. The more songs she can find to draw out her unique persona, the better.

3. Lauren Alaina, 16 (Rossville, Ga.)

When Ryan asked her how it felt to be compared to both Kelly Clarkson and Carrie Underwood (and Kellie PIckler), Lauren responded: “I’m just Lauren.” So what do we know about “Lauren” so far? She’s got a brilliant set of pipes and a penchant for country music, but we’ve yet to fully grasp the artist behind the voice.

It’ll be crucial for Lauren to use the next 13 weeks to showcase both her artistry and her voice, choosing songs that don’t merely mimic her influences but build on them. If she can accomplish this, she’ll fly straight to the Nokia Theatre.

4. James Durbin, 22 (Santa Cruz, Calif.)

I’m still not convinced James can get his pitch problems under control — and that’s a big issue for me — but his impressive Judas Priest performance last week was his best attempt yet. He has believability and rock cred on his side, and that will carry him through at least the next few weeks.

5. Ashthon Jones, 24 (Valdosta, Ga.)

Ashthon’s got a big voice and a fiery personality that falls right on the good side of “diva.” That’s a lively combination, but it’s yet to be seen whether or not her voice is strong enough to stand up against some of the more substantial voices in the competition.

6. Stefano Langone, 21 (Kent, Wash.)

After sinking with Bruno Mars' chart-topper “Just The Way You Are,” Stefano delivered a stunning, heartfelt performance of the gospel ballad “I Need You Now” when picked as a wildcard candidate, proving the importance of song choice. He’ll need to choose songs wisely and intuitively over the next few weeks so as not to fall into the same trap.

7. Jacob Lusk, 23 (Compton, Calif.)

Jacob finally dialed down his massive voice on a more straightforward (and outstanding) cover of “A House is Not a Home” last week. With a talent as immense as his, knowing how and when to reign in his rich voice will be his main challenge going forward.

8. Scotty McCreery, 17 (Garner, N.C.)

On one hand, it’s nice to see some balance in the Idol country camp this year, thanks to Scotty’s neo-traditional leanings. On the other hand, while he sailed through pitch-perfect renditions of “Long Black Train” and “Letters From Home,” each felt a tad paint-by-number.

The key to his success will be finding ways to infuse individuality into his performances.

9. Paul McDonald, 26 (Huntsville, Ala.)

Quirky, floppy-armed Paul charmed the audience and judges alike with his infectious rendition of “Maggie May” last week. His voice (and persona) is unlike that of any contestant we’ve heard before on Idol — and as we’ve seen in the past, that could work either for or against him as the competition progresses.

10. Thia Megia, 16 (Hayward, Calif.)

Thia has a fantastic voice and a pure tone that, as Randy pointed out with his Michael Jackson comparison, is special in a way I can’t quite put my finger on. Of all the contestants, though, we know Thia the least.

Who is she? What drives her as an artist? If she can learn to let her guard down and form more of an emotional connection with the audience, she’ll make a bigger mark on the competition.

11. Haley Reinhart, 20 (Wheeling, Ill.)

Haley’s performances thus far have been memorable — but not for the right reasons. The bluesy singer has a tendency to kill the natural groove of songs by wringing out her notes and throwing in affected growls and runs.

She could use a not-so-gentle reminder (paging Debra Byrd) that emotional energy comes in many forms and doesn’t always require a seven-note-per-second vocal performance.

12. Karen Rodriguez, 21 (New York, N.Y.)

Last season, I might have understood Karen’s inclusion in the Top 13, but she seems a little out of place this year amongst the more distinct and potent voices. Her performances — like last week’s half-English, half-Spanish “Hero” — have been pleasant and sincere, but ultimately forgettable.

13. Pia Toscano, 22 (Howard Beach, N.Y.)

I wrote Pia off as unremarkable in my last recap, but she proved me wrong with one sturdy, searing cover of “I’ll Stand By You.” A swirl of conviction, power and gorgeous note choices made it a standout performance.

It’ll be interesting to see if she’s able to build on this momentum going forward in the competition — if so, she’ll be a contender for the finals.
