Some band member replacement have shined, other total failure. What are your thoughts on the topic. Here are a couple that come to mind.
Niel Peart for John Rutsey drummers for Rush. While Rutsey appears on only one album their first, it's clear that Peart helped shepherd Rush into a new and well defined direction as well as being recognized as one of rocks best drummers.
Sammy Hagar for DLR, ok this one will be a bit controversial for some, but for me the DLR VH version has much more rawness and un-refinement as well as swagger that the SH version misses. Sure the SH version had more commercial success, but that does not in itself mean they were better, a discussion for other threads already out there.
What are some of your favorite and or least favorite band changes?
