When
Rock is the sound of the back half of the 20th century. When did it crest, and what's still pulsing?
Career starts (5-year buckets)
When each entity began making music, split between bands and solo artists. Career start = formation year for bands, debut album year for solos.
- Bands
- Solo artists
Average career length by era
Mean active years from career start to dissolution (or today, if still active).
Studio releases per year
Sum of all studio albums across the archive, by first-release year. Peak: 269 releases in 2012.
Where
Rock travels — but bunches in specific neighborhoods.
Top countries
UK and US dominate, but 33 countries appear across the archive.
Top origin cities
Cities that produced the most entries (curated bands + solo artists). From Wikidata's origin-city tag.
Punching above their weight
Countries with at least 5 entities, ranked by lowest average rank. Lower average rank = entries cluster nearer the top.
Who
The gang versus the solo voice. Rock comes in two shapes — and bands themselves come in many sizes.

What
Rock subdivides — and shifts decade to decade. Here's the shape of those subdivisions.
Genre coverage (primary or secondary tag)
Each entity carries two genre tags. Counts are the union — Classic Rock and Hard Rock dominate by design, since they're the umbrella tags for the 1960s–70s canon.
Wikidata genre spread
Genre tags from Wikidata that aren't in the curated list — surfacing the long tail (post-hardcore, shoegaze, math rock, dream pop, et al.).
Genre over time
Top 6 primary genres, plotted by founding decade. The shape of how rock's center of gravity moved.
- Classic Rock
- Indie Rock
- Pop Rock
- Alternative Rock
- Hard Rock
- Folk Rock
