Partners In The Search
The Jack & Jill Rosenthal Foundation is powered by people and organizations who believe every missing child deserves answers. From Band X and its benefit concerts to corporate sponsors, community partners, and generous donors, each plays an important role in advancing our mission.
Together, their support helps fund investigations, expand public awareness, and bring hope to families still searching.
Band X
Band X was born from a friendship forged through music. In the early 1980s, Paul Jack Fronczak, Darren Valen, Rick Holland, Dan Badaluco and Henry Zappia came together in Tucson, Arizona, where they spent five years performing throughout the local music scene and building a loyal following.
Decades later, their passion for music—and for each other—brought them back together for a series of successful reunion concerts in Tucson. In 2025, Band X performed a benefit concert supporting a veterans organization, welcoming Tracey Hastings as guest lead female vocalist.
Today, Band X has taken on a new purpose. United by friendship and a shared commitment to making a difference, the band performs benefit concerts to raise awareness and critical funding for the Jack & Jill Rosenthal Foundation. Every performance helps support the Foundation's mission to bring answers, hope, and justice to families of missing and unidentified children.
