MTV reports that members of Big Star, R.E.M., She & Him, the Posies, and X are joining together Saturday night at the South By Southwest Music Festival to honor Alex Chilton, the Big Star/ Box Tops singer and guitarist who died of a heart attack on Wednesday. He was 59.

Chilton was scheduled to front Big Star during a SXSW performance on Saturday night at Antone’s. Now, the occasion will be transformed from a simple rock concert to a howling rock ‘n roll elegy: the remainder of Big Star will be joined by Mike Mills of R.E.M., M. Ward of She & Him, John Doe of X, and many others for a live performance of Chilton’s music and a tribute to his legacy.

Original Big Star drummer Jody Stephens recently spoke to Billboard about the tribute performance:

“Certainly where Alex and I connected over the years was through music, either in the studio or onstage, so I think that’s a great way for us all to tip our hats to Alex and celebrate his life.”

For those readers who happen to be in Austin this weekend, I highly suggest you get in line early for this one—like Chilton’s indelible music, it’s not something you should miss.

What do you think of the tribute show lineup?
