Legendary Guitarist Lou Reed Dead at 71

Lou Reed, a highly influential songwriter and guitarist most known for his work with The Velvet Underground and a strong solo career, died Sunday at the age of 71, according to a report from Rolling Stone.

Rolling Stone's story does not pinpoint a cause of death, although Reed underwent a liver transplant in May.

While Reed never experienced a highly successful career financially, he is often seen as one of the most influential artists of his time. He is seen as a highly experimental guitar player who also went to greater depths in his songwriting, often penning songs about sexuality and the drug culture of the time.

He also did a full-length collaboration with Metallica on the album "LuLu" in 2011.

Reed married Laurie Anderson in 2008.
