You can't have a discussion about 80's music trends without the words "keyboard" or "casio" being brought up. They're what made 80's music so great memorable. Below are a few ads from various Rolling Stone magazines featuring just four of the dozens (I'm guessing) of different versions of these mini electronic pianos.
I'm sure the Boss thought he was doing Casio a favor to grace their ad with his face, until we see who the company's other spokes model was (below).
"Where miracles never cease."
There weren't many contenders to Casio, but Fisher sure had a practical idea of combining the keyboard with the jambox (now there's a whole 'nother topic!)
