heck yes. BTW, an amazingly good Big Star CD if you can find it is called Columbia. I got a copy in a random small second hand store. It's from a reunion show at some college in 1993 - Alex Chilton was around, they asked him to play a Big Star gig and he said 'sure, why not?' They pulled a band together for it (couple of guys from the Posies along with Alex and Jody), and it's an amazingly good show. They even played Chris Bell's 'I Am The Cosmos', from his solo album released before he died (it's also called I Am The Cosmos, definitely buy it if you can find it, too). They're inexplicably unknown outside music geeks, but massively influential and very well-respected by musicians.
Oh, and finally, Sister Lovers is more of an Alex Chilton solo album, according to the history. He wrote it all and he's pretty much the only consistent artist, the rest of the music was done by a wide range of people. Radio City and #1 Record are the only true Big Star studio albums, sadly. Sister Lovers *is* a great record, though, for all its oddness - Holocaust and Kanga-Roo are amazing tracks.
