Thousands of concerts every year go completely unregistered. No ticketing, no listings, no data, and therefore no proof they even exist. Jamr maps this invisible half of the live music scene: from small bar stages to festivals, all indexed and searchable.

Huub Kuiper explains how Jamr turns this fragmented landscape into a structured live music dataset, and what this makes possible: an app that helps fans discover what’s happening tonight, and an analytics tool that gives venues and bookers insight into what’s happening in their market. Plus, the first insights and figures from the dataset.
