American Idol's Top 24 Perform: Who Gets Your Vote After Night 1?

Disney's Aulani Resort was swept by a wave of talent on Sunday as the first half of American Idol's Top 24 performed on the beach, this time aiming to win over the viewers at home.

That's right, friends and frenemies, voting on Season 23 is officially open. And since Carrie Underwood, Lionel Richie and Luke Bryan have apparently taken a solemn oath not to give any real criticism this season, I guess that leaves the honesty up to us. So let's buckle up.

In addition to Jelly Roll, whose debut as Idol's first-ever artist in residence earned an "A" from 65% of TVLine readers, the contestants were given pointers by the legendary Ashanti, who also blessed aging millennial viewers with a medley of her classics. Seriously, the first few notes of "Foolish" had me reaching for the Metamucil. How is that song 23 years old?!

Sunday's episode gave us an eclectic (and mostly very good!) mix of performances from Ché, Penny Samar, Kolbi Jordan, Baylee Littrell, Victor Solomon, Gabby Samone, MKY, Zaylie Windsor, Breanna Nix, Isaiah Misailegalu, Slater Nalley and Jamal Roberts, with the other half of the Top 24 set to perform on Monday night (ABC, 8/7c).

Read on for a breakdown of Sunday's Top 24 performances, complete with videos as they become available, then drop a comment with your thoughts and vote for the singers you'd send through to the next round.

Ché had all of Aulani grooving to his effortlessly cool take on Stevie Wonder's "Master Blaster (Jammin')" — a song choice I wouldn't have predicted in a million years. Smooth in all the right places, with just enough runs sprinkled throughout, this performance set the bar pretty high for everyone else. This was more than reggae. This was... Ché-ggae.

Following Jelly Roll's advice to keep being her "weird, awkward self," Penny fully let loose on stage with her performance of Chappell Roan's "Good Luck, Babe!" She excelled in the song's earlier, softer moments, and she even nailed a few of those tougher high notes. Overall, though, it felt like she just tried to do too much and got lost in the sauce. And it's a shame, because I know she's better than this performance. As Elle Woods would say, Penny has all the equipment, she just needs to read the manual.

After struggling through Hollywood Week, Kolbi made a heck of a comeback in Hawaii, reminding everyone why she snagged a platinum ticket. And what better way to display her new attitude than with Patti LaBelle's song of the same name? Kolbi's personality came through so clearly as she effortlessly navigated the song's ups and downs. Even Baskin Robbins would be impressed with the number of flavors she was able to work into this performance.

Andy's Grade: "A"

There's an inherent joy to Pharrell's "Happy" that was missing from what Baylee gave us on stage tonight. Sure, I clapped along, but my figurative room very much had a roof. Overall, I'd say it was a fine performance, but if he wants to be seen as more than a mere Backstreet Baby, he'll need to step it up.

Andy's Grade: "B"

Choreography? Costuming?! This is one of those performances that could have easily gone wrong... but ended up going very, very right. Victor showed a new level of versatility and fearlessness by putting his own spin on Luke Bryan's "That's My Kind of Night." Sexy, soulful and totally unexpected, this one was a joy to watch once I was able to fully wrap my head around what I was witnessing.

Andy's Grade: "A-"

Impossible not to root for, Gabby has been one of my Season 23 favorites from the moment she hit the screen, and she more than met my expectations in Hawaii. Instantly stirring, then all-out powerful, her performance was Celine Dion's "It's All Coming Back to Me Now" was one of the night's best, complete with a powerful finish. That third "BABY!" will live with me for the rest of the week.

Andy's Grade: "A"

I initially wrote MKY off as being too gimmicky (to be fair, the guy does spell his name with three capital letters), but the more I'm exposed to him, the more I feel like I see him as a legitimate artist. That smooth high note at the end of his take on Miguel's "Adorn" was the perfect cap to an overall impressive performance.

Andy's Grade: "B+"

One of the lucky few sent into the Top 24 early, Zaylie was tasked with coming out of her shell this week; both Jelly Roll and Ashanti encouraged her to engaged more with the audience, even if it was just a few glances. Overall, I'd say she followed their advice, turning out a version of Blondie's "Heart of Glass" was uniquely her own. Most of the performance was fun, but Zaylie encountered a few high notes that didn't quite agree with her. It was good, just not great.

Andy's Grade: "B"

Sometimes I wonder if Breanna is truly aware of the power she wields. From the second she stepped on that stage, she owned Lauren Daigle's "Still Rolling Stones," pummeling us with every note. While other contestants struggled to connect with their songs, Breanna didn't even have to try. She simply got up there and lived it, as if she had put the pen to paper herself. If she keeps this up, we could be looking at a real contender.

Andy's Grade: "A"

Even if Isaiah didn't tell us that Maoli's "You Can Have It All" was his mom's favorite song, you could get a sense from his performance that he's been singing this one for years. This was another excellent showing from the artist known as Samoan Silk. Good vibes, great vocals, no complaints.

Andy's Grade: "A"

I've envisioned Slater going all the way from Day 1, and I'm only more confident after his authentic, emotional and delightfully growly take on Judy Garland's "Over the Rainbow." This was a fantastic performance, one that showcased what Slater has to offer as an artist.

Andy's Grade: "A"

Idol knew exactly what they were doing saving Jamal for last. An explosive way to end the night, he told a full story with his performance of Jelly Roll's "Liar." I thought I knew what I was in for when Jamal had the songwriter himself sobbing during rehearsal, but he took it to a whole other level once he got on stage. Strong from the start, his growl and intensity gave me chills — and that stool kick? OK!
