Mainly TV and radio, like all the other old(er) gits here.
Top of the Pops, August 1979... up until then, there hadn't been anything musically that really moved me, but suddenly there was this https://youtu.be/qU7pIVt29Bw?t=1495 and my world changed.
After that I started opening my ears. While my mates would be listening to Thomas the Vance and his Friday Rock Show, I was tuning into Capital for David Rodigan's 'Roots Rockers'.
