Mexican-American famous guitarist Carlos Santana and rapper Nas hit the stage at Lopez Tonight on TBS last night to perform their new collaboration "Back In Black" - This remake of AC/DC's hit song is included on Santana's latest concept album entitled "Guitar Heaven: The Greatest Guitar Classics of All Time" which is in stores NOW. That was a hot performance! Loving the song, from the hardcore rock feeling, the amazing female background vocals to Nas' rap addition. Carlos Santana is simply incredible at what he does. Let's see if his version of the classic "Black in Black" performs well on the charts..
