People don't really remember a lot from it, but the '20s (in my opinion) were the absolute best time for music (shortly followed by the folk movements in the '60s)
It's the Twenties and there's Prohibition. You take a taxi into the booming New York City late on a Friday night. You walk into the slums and hear the faint rhythyms of music. As you draw closer, you find it a bustling square centered around a lit night club. You take a step into the smokey air. How beautiful and fresh the birth of Jazz and Blues soothes your eardrums, I cannot tell.
So, the birth of Jazz in the '20s, and the Folk movements in the '60s. Not the Beatles crap, but the Crosby, Stills, Nash & Young, Joni Mitchell, Bob Dylan, Arlo Guthrie, and the Simon and Garfunkel..can't beat it!!
