Adam Schlesinger, the co-founder of pop-rock band Fountains of Wayne and an Oscar-nominated songwriter, has died from complications related to coronavirus. He was 52.

“As many of you are aware, Adam had been hospitalized with Covid-19 and although he had been making some small improvements over the last few days, Adam’s condition was critical and he was ultimately unable to recover from Covid-19 complications,” read a statement from the band’s attorney, provided to CNN. “He was truly a prolific talent and even more so, a loving and devoted father, son and friend.”

He co-founded Fountains of Wayne with Chris Collingwood, which earned two Grammy nominations in 2003. One for best new artist and for best pop performance by a group for the Top 40 single “Stacy’s Mom,” that became the band’s biggest hit.
