Prior to releasing their full length disc, Running Wild, Airbourne released an 8 song EP, Ready To Rock. This disc had a very limited pressing, and is out of print.
Fans all over the world are out to get this one, (self included). Another copy recently turned up on EBAY and sold for a whopping $410.00.
I believe in paying for music, but $51.25 a song is a bit much.
