Friday night I had the pleasure of seeing a live performance by a friend of mines daughter, who played the lead, Dorothy. Here is my review.
I took in the Norco Rockstars of Tomorrow performance of The Wizard of Oz.
What a treat it turned out to be. The performance was located in a building tucked into the corner off Hamner. Its a nice cozy place to teach and learn the arts, rent studio time and showcase talents. This is where this nights performance took place, the Showcase Room. It's a nice size stage. I walked into the room that was filled with a haze, It felt like I had indeed stepped into the Emerald Forest itself. I even took a quick look around for those pesky flying monkeys.
The show's actors was a mix of different age groups, kids form seven to teens, with a couple of adults mix in.
My anticipation was at its peak after a brief introduction from the Producer of the show. The lights dimmed and the show began.
Enter Dorothy and Toto. Dorothy is played by Ellie Roy and she gives a stellar performance alongside Toto, played by Hailie Lopez.
Throughout the play Ellie Roy knew her lines and delivered them with ease.
Then she started that first song of the show, Somewhere Over the Rainbow, and her star got even brighter. She can sing.
The whole cast can sing. I was pleasantly surprised.
The neighbor, Miss Gulch that wanted to murder Toto and also played the Wicked Witch played it so well that I wanted to go drop a house on her myself, and ask, "How do you like that My Pretty"
The scarecrow, played by Connor Vamum, really researched this role, and having seen Ray Bolger's scarecrow, I could see him utilizing all those facial ticks that the original Scarecrow incorporated into the role.
The Tin Man, played by Lilli Tran, and the Cowardly Lion played by Laveen Maxwell, were equally superb. The cast had no issues knowing their lines and even pulled off the many tongue twisters sewn into the script.
The timing by the performers during the many humorous pieces of dialogue was right on and drew much laughter from the audience. The choreography from the supporting cast was pleasant to watch as it made me want to jump up on stage and join in the dancing and singing.
Overall, this was a well produced show executed by a refreshing cast of kids, who are all indeed Rockstars Of Tomorrow

Hi AB,
Thank you so much for taking the time to share such a thoughtful and detailed review. We truly appreciate your kind words and are grateful you joined us for our Wizard of Oz performance. Our cast and crew put their hearts into bringing this show to life, and it means a lot to know the experience resonated with you.
We’re especially thankful for your recognition of the students’ hard work, talent, and dedication. Seeing our young performers shine on stage is exactly why we do what we do, and your 5-star review encourages them more than you know.
Thank you again for supporting our program and celebrating these incredible Rockstars of Tomorrow. We hope to see you at the next show!

I just wanted to say thank you to Jeremy he is one of the most patient, kind and knowledgeable instructors that my grand daughter and my three other grandchildren have had the opportunity to work with. He has worked with all of them thru Jam Corp and two of them with guitar lessons. All of them look up to him and think he is a great guys. Watching the way he interacts with all the kids in Jam Corp is amazing, never gets upset with the kids, always helpful and always has a smile. Just want to say we all think you are the best. Thank you Jeremy for the great job you do.

My wife and I highly recommend "Rock Stars of Tomorrow". My girls have been taking piano lessons from Coryn for quite sometime and they absolutely love her. Not only is Coryn great with my girls, she is an extremely talented pianist and she has a beautful singing voice. I truly hope that she stays with Rock Stars of Tomorrow for awhile, because she is a natural born musician and teacher. Coryn, thank you for making the learning process so fun and engaging for my girls. You are a Rock Star!!!
Response from the owner · a year ago
Thank you so much for the kind words and 5 STAR review. We love Coryn too!!!! She actually started with us as a student when she was about 7 years old, so it’s been really exciting to watch her grow into the incredible musician and teacher she is today. We’ll definitely make sure she sees your message. It means a lot, and we’re so glad your girls are having a great experience with her. Thank you so much!!!

I just wanted to show my appreciation for Frosty. I know my kids work with different teachers and they are always amazing but this is for Frosty. We have been taking lessons since 2018, never stopping even durning COVID. He has been such a great teacher and mentor to my son. To see how much time and effort he puts into his students. By putting together the drum recital for these kids and letting them show off to friends and family about all their hard work is simply amazing. I think we just did our 7th or 8th recital with him and I just wanted to make you aware of what a great teacher you have here. I’ve had people come see Cash and were blown away by all these talented kids. I always speak highly of this amazing business/ home that Michael has have created for these kids and for that I have to say thank you!
So I just wanted to let you know how great Frosty is at Norco Rockstars. Also we appreciate Dakota for always being there with support as well.
Response from the owner · 2 years ago
Hi Jackie!! Love this review! I know we are lucky to have Frosty teach at our Norco school. He's a rare talent and really knows how to positively inspire young musicians of all abilities. This means a lot that you took the time to share your thoughts. I promise to share this with Frosty as he will be thrilled. Thank you again for this awesome message!!!!
