Primus frontman Les Claypool is sad to report that his nephew Matthew has passed away after struggling with Infant's leukemia for the past two years. The bassist-singer brought Matthew's struggle to light last year when auctioning off one of his basses to raise funds to help offset his brother's family's mounting medical costs.
A couple of days ago, it was announced that Primus bassist/singer Les Claypool would be auctioning off a rare prototype of his Pachyderm bass to benefit his two-year-old nephew, Matthew. Claypool's nephew is suffering from a rare form of infant leukemia and is undergoing bone marrow treatment. With the medical costs rising, Claypool is putting his bass up for auction on eBay to help pay for Matthew's treatment.
