“There are very few records whose influence can be so strongly felt after 45 years as the Kinks’ ‘You Really Got Me.’ It is the song that has been widely touted as the blueprint for hard rock and heavy metal, long before the likes of Black Sabbath and Led Zeppelin came along,” (SoundOnSound). ” … the jarring, distorted two‑chord riff that opens the track and continues behind the lead vocal, and the fierce, deliberately sloppy guitar solo … paved the way for punk rock.
A UK chart‑topper in September 1964, and a number seven hit in America at the height of the so‑called British Invasion, ‘You Really Got Me’ was not only the breakthrough number for North London outfit the Kinks, but also a landmark recording that inspired the Who’s Pete Townshend to compose ‘I Can’t Explain’, and whose influence resonates to this day. All of which was quite an achievement for a group of teenagers who had only formed the previous year, and their innovative producer, who hadn’t been around a whole lot longer.
… In his 1984 book The Kinks: The Official Biography, author Jon Savage wrote, ‘What (producer) Shel Talmy and the Kinks did … was to concoct the perfect medium for expression of the adolescent white aggression that has been at the heart of white popular music …’ Those involved in its creation apparently agree. ‘When I left the studio I felt great,’ recalled Ray Davies, whose fruitful efforts on behalf of the song established him as the chief composer and — at least in his eyes — the leader of the Kinks. ‘It may sound conceited, but I knew it was a great record… I said I’d never write another song like it, and I haven’t.'”
The colorless guitar power chords don’t give any indication of the track’s tonality, but at 0:21 the slightly uptuned G-based two-chord riff shifts to a riff centering around A. It’s the vocal melody, using a major third degree of each chord, which gives away both the G and A chords as major. At that point, it’s spelled out that the A chord isn’t actually a ii chord within the context of G major, but rather a new tonic chord (a key change from G major to A major). More changes continue from there.
