Legendary Aerosmith guitarist Joe Perry this week released his first-ever collection of holiday songs.  Titled Joe Perry's Merry Christmas, the EP contains four songs and features a contribution from renowned actor Johnny Depp, an accomplished guitarist in his own right.  Two of the songs ("White Christmas" and "Silent Night") are instrumental versions of Christmas classics, while the other two were made famous in the 1950s by Chuck Berry ("Run Rudolf Run") and Elvis Presley ("Santa Claus Is Back In Town").  Depp plays rhythm guitar on "Run Rudolf Run".  The EP is currently available for download on iTunes or at UnisonMusic.com.   In an interview, Perry noted that he has wanted to do a Christmas album with Aerosmith for many years, but the band never seems to have the time for a holiday side project.
