I want you to pretend...
It's January 1969 and you're a teenager. A friend comes over with a record album she just got and says, "You gotta hear this!"
You look at the album. It's a band with a funny name that you've never heard of before. That's not a surprise since six months earlier, the band didn't exist and it's only been a few months since they first performed in public. They don't even have a record contract. The lead guitarist paid for the production of the album out of his own pocket and a childhood friend engineered it. It had to be done fast and cheap so they recorded it in less than 36 hours.
Your friend puts the album on the record player and she turns it up to 11. Power chords begin to burst from the speakers and by the end of the four songs on Side A, your mind is blown.
