dear Mike
1) obtain some waterproof speakers
2) obtain the Painkiller (Live in Nagoya '94) tour album "Talisman"
3) put Talisman on stereo
4) fill bathtub with water (use blood if you prefer)
5) turn speakers to 11
6) put speakers in tub
7) put head in tub
After about half an hour of this you will understand why whales beach themselves when the Navy tests out its new sonar system!
