“CANCER MERCHANT”

At the tender age of 15, David Matthew Olson aka “Daveo Mathias” began rapping under the name “Cancer Merchant” to record diss tracks against the bullies at his high school, 50 Cent, & more.

Over the next two decades, Cancer Merchant continued sporadically dropping beautifully-crafted Dadaist bangers full of silly absurdism, provocative political commentary, and philosophical trippiness - with fire beats of brilliantly flipped samples and lyrics that will one day win the Nobel Prize in Literature.
