The NISV knowledge graph for broadcast concerts. This knowledge graph contains metadata of more than 75,000 concerts broadcast on Dutch public service TV and radio. The source of the knowledge graph is the archival metadata stored at the Netherlands Institute for Sound & Vision.
The concerts (and the rest of the NISV archive) are available via the Sound&Vision SPARQL endpoint. The exact concert collection can be accessed via the query in this link
Each concert has its own license, determine using the NISV rules for licensing. Where possible, this is a CC license. The license is stated in the triples for that concert.
This knowledge graph is further documented in this data story and this blog
