Maiden United

Maiden United are an Iron Maiden cover band that plays classic Maiden songs completely acoustically. While that may sound horrible, it actually sounds pretty fucking good. The band creates a completely different atmosphere than the original classics. On their album "Mind the Acoustic Pieces" they have very good covers of songs like Where Eagles Dare, The Trooper, Die With Your Boots On, and Flight of Icarus.
