First book from rock band (7)
I believe the answer is:
genesis
I believe this clue is a double definition.
'first book' is the first definition.
(I've seen this before)
'rock band' is the second definition.
(I've seen this before)
'from' is the link.
(Other definitions for genesis that I've seen before include "Beginning (in the Bible)" , "rock band" , "OT opening" , "Old Testament Book 1" , "name of group" .)
