Drive erratically to see composer (5)
I believe the answer is:
verdi
'composer' is the definition.
(Italian composer Giuseppe Verdi)
'drive erratically' is the wordplay.
'erratically' indicates anagramming the letters.
'drive' is an anagram of 'VERDI'.
'to see' acts as a link.
(Other definitions for verdi that I've seen before include "Diver became a strange composer" , "Emblem of the Knights Hospitallers" , "Opera producer" , "Drive to meet great composer" , "Giuseppe _____, composer of "La Traviata"" .)
