NMTB and 'New Rose' by the Damned are the album and single were immediate and made the most instant impact on my teenage self.
Going along to the Apollo and other small venues several times a month from 1979-84 will never be beaten. The Fall, Skids, DEVO, Ramones, Sham 69, Rezillos, Jam, Undertones, Boomtown Rats, Siouxsie, Cramps, Jam, Undertones, Teardrop Explodes, Orange Juice, Gang of Four, Pere Ubu, Delta Five, Adam and the Ants, Bow Wow Wow, Specials, Selecter, Madness, Talk Talk, Simple Minds, Echo and the Bunnymen, Altered Images, Fire Engines, Vapors, PiL.... the list goes on.
There was never a better time for music IMO.....but everyone will have their own memories.....
