Growing up in the 80s, my taste in music was pretty well influenced by MTV. The artistic and sexual aspects of video both caught my eye as a young teen boy who took a lot of art classes. For better or worse, music videos helped form my visual aesthetic and expanded my musical appreciation.
Aerosmith was one of those bands that I got into probably mostly because of their videos. I'm glad because they've put out solid albums for a long time. From Peter Gabriel's "Sledgehammer" to Tool's "Sober", here're some other musicians that I don't know if I would have given much attention then if it hadn't have been for MTV:
Guns N' Roses
Faith No More
Red Hot Chili Peppers
That video of "Sober" still gives me chills. I stopped at '93 with MTV's yearbook because that's when I graduated high school and started getting most of my new music from random finds in record stores and the radio.
I know there're a lot more videos that were instrumental in popularizing certain groups. Who wouldn't you be a fan of if it weren't for MTV?
