New management outfit Grandview Music launches

Experienced managers Graham Martin, Diony Sepulveda and Kimberly Schon have launched Grandview Music, a new artist management company based in Encinitas, San Diego, California.

Martin will serve as the company’s CEO, with Sepulveda as president and Schon as executive vice-president. Grandview Music’s rock-focused roster includes the likes of Rise Against, the Story So Far, Pepper, Quicksand, Bad Child, Militarie Gun, Asking Alexandria, Motionless in White, Lowlives, and the Messenger Birds.

Martin began his management career at Valvet Hammer Music Management, working with clients including Deftones, Alice in Chains and Pepper. In 2014, he joined Pat Magnarella Management, which relaunched in 2018 as Grndvw.

Sepulveda has worked with artists including Pennywise, Avenged Sevenfold and Slipknot. He most recently worked at 5B Artist Management, where he ran Slipknot’s touring business, in addition to signing Asking Alexandria and Hollywood Undead.

“It’s very rare that in this journey you get to join forces with such extraordinarily talented, like-minded and passionate friends”

Another 5B alumnus, Schon has managed acts such as Stone Sour, Motionless in White, Lowlives and Slipknot, helping to launch the latter’s music festival Knotfest internationally. She launched her own management company in 2019.

“Diony, Kim and I have a deep passion for what we do and strive to work with culturally relevant artists,” says Martin, “while building a music company that reaches far beyond the status quo of what an artist management company is.”

“I have been lucky enough to work alongside some of the most respected and innovative industry professionals and artists the last 20-plus years,” adds Sepulveda. “It’s an honour to be working with Graham and Kim as I have incredible respect for what they have accomplished in their careers. I’m very excited for this next chapter of creating a new unique modern music company with my friends.”

Adds Schon: “I got into this business with the goal of helping foster the voice of the next generation of artists. It’s very rare that in this journey you get to join forces with such extraordinarily talented, like-minded and passionate friends as Graham and Diony.”
