If you could go back in time and stop any one person or group's musical career, who or what would it be?
This isn't a "go back in time and assassinate" someone question. It's just their musical career never takes off and thus any music they ever would have made is no longer in this timeline.
Oh boy, yeah, a lot more came out about it. There's actually been a lot over the years, but a few years ago a pretty serious documentary came out about it.
