Ed Note: This was totally out of the blue. Alex was going to be performing with Big Star at SXSW, but he was rushed to a hospital yesterday and died of what is believed to have been a heart attack. Here are some additional highlights from his amazing career, starting with the legendary Replacements tribute to his work and influence:
