I saw him at Mutiel Andersons All Star Guitar Night at the NAMMM show many years ago. Watching him and Tommy Emmanuel play off each others style. Shortly Tommy was almost outdoing Preston at the percussive tapping. Preston tried to mimic some Tommy licks, and had fun. Preston was best in his own element, Tommy was on fire that night and in a tasteful but powerful way among a long list of GREAT musicuans at the event, was unequaled.
