My Take

Alexander 23 fascinates me because he thrives both in front of the microphone and behind the boards. Coming out of Deerfield, Illinois, Alexander Glantz built a remarkable songwriting and production resume, working with Olivia Rodrigo, John Mayer, Noah Kahan, Tate McRae, and Selena Gomez among many others. That breadth of collaboration tells me artists trust his ear and his emotional honesty, which is no small thing in pop. I find the most durable careers belong to those who can both create and craft for others, and he clearly has that dual gift. I am genuinely curious to hear where his own sound goes next.
