Well you might be asking what this has to do with Rajiv Gandhi Airport , Hyderabad, India. Just that the photo was taken from inside the waiting lounge where there is a "Hard Rock Bar" and these instruments are supposed to be used by "Hard Rock artists". I wonder if they are original. They have made a "Rock Museum" over there.
The begining one are from the band "Megadeth" . I'm not femiliar with such bands. Google it if you want.
