She Wants Revenge "Tear You Apart" VS The Knack "My Sharona"
Granted, the guy just wanted to do a creepy remix of a creepy song, but when you try to remix She Wants Revenge, if you do it with anything from the late 70's/early 80's, it is overkill. She Wants Revenge is a great band that has somehow managed to appropriate and expand on several different styles from that period and create an excellent album. I did like the mix, though, being a big fan of The Knack as well.
Justin Warfield, one of the pair behind SWR, also created one of the best trip-hop albums I have ever heard, "My field trip to Planet 9." Again, he is just great at borrowing styles and making them his own.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
