What EVH represents is the R&R guitarist who came out of the dying Classic Rock period(which doesn't go beyond mid 70's or so, IMO) and introducing things truly revolutionary that just about ALL Rock guitarist moving forward, acknowledge.
I quickly lost interest in VH after their 2nd LP. Saw them in 78 when their debut came out and they were doing their first rounds of arena concerts not long after doing Pasadena backward parties and Holliday Inns and the LA clubs.
Ted Templeman produced the debut LP-Anyone who also listened to early Montrose knows the BIG SOUND of those albums. No audiophool LP needed.
