From KPBS and PRX, “Port of Entry” tells cross-border stories that connect us. In our recurring “Moved by Music” series, we travel back in time to get a little taster of the early electronic music that set young Amezcua’s imagination on fire. We explore some of the futuristic synths and drum machines back in the 70s, the synth pop he was digging for at record stores in the 80s and the artists that inspired him in the 90s when he was playing raves all over Mexico.
