Memphis singer-songwriter Alex Chilton has passed away aged 59.

The musician died on Wednesday morning after suffering a suspected heart attack. According to the Commercial Appeal, he had been complaining about his health earlier that day before he was taken to the hospital by paramedics.

John Fry, a friend of Chilton's and owner of Memphis' Ardent Studios, said: "I'm crushed. We're all just crushed. This sudden death experience is never something that you're prepared for. And yet it occurs."

Chilton joined the Box Tops at the age of just 16, where he had success with the hits 'The Letter' and 'Cry Like A Baby'. When the band broke up in 1970 he formed Big Star, who would also disband after three critically acclaimed albums, as well as pursuing his own solo career.

He had also been scheduled to perform with Big Star at this year's South by Southwest festival.

Our condolences and thoughts go out to Alex's friends and family at this time.
