I recently presented some new stuff I have been working on at the DC TUG event. Here is a link to my presentation. I discussed my Beatles analysis viz as well as comparison of Beatles' song sentiment with Tupac, rap speeds, chord patterns, and the lyrical progression of Blackalicious's Alphabet Aerobics.
Below is a slide from the deck. Here is my original sketch of the Beatles' viz and a comparison with the final visualization. Thank you Brittany Fong for the invite.
