Luke seems like the type of guy who would be obsessed with the guitar solos in stuff like Free Bird (https://www.youtube.com/watch?v=0LwcvjNJTuM 4:46) or Electric Eye (https://www.youtube.com/watch?v=eGtwgYt_QnA&list=RDeGtwgYt_QnA&start_radio=1) as the type of stuff he personally plays on his guitar.
