Goofing around with golang to learn. What better way than to explore GD shows? Fetch Grateful Dead shows from archive.org and index them to Elasticsearch to answer interesting questions, e.g.:

• Favorite years? '72 and '77? ;)
• How did setlists change over time?
• How did venues change over time?
• Distribution of songs - e.g. when did they appear/disappear from shows? How does that map to band makeup?
• Correlation of certain songs to higher reviews?
