CHICAGO (CBS) – Jeff Castelaz, co-founder of Dangerbird Records, started an online blog when his 4-year-old son Pablo Thrailkill Castelaz was diagnosed with bilateral Wilms Tumor, a rare form of childhood cancer.

After a year long battle his son passed away a few days after his 6th birthday. Using the energy of music to help drive the mission, the Pablove Foundation was born. The mission of The Pablove Foundation is to fund pediatric cancer research and advances in treatment, educate and empower cancer families, and improve the quality of life for children living with cancer through hospital play, music and arts programs.

The Pablove Foundation is named after Pablo Thrailkill Castelaz, the son of Jo Ann Thrailkill and Jeff Castelaz.

Imbued with his spirit and inspired by his strength, Pablove is dedicated to the daily, global fight against childhood cancer and the suffering that comes in its wake.

CBS 2 and Blackbox frontman Damon Ranger sat down with Jeff at the 3rd annual Pablove Benefit Concert at Milwaukee’s Turner Hall, where 12 artists including Butch Walker and the Black Widows performed to raise money for children’s care through the Pablove Foundation.
