I am not familiar with the catalog of Jarvis Cocker, formerly of the band Pulp, so this one came to me in my usual haphazard way, from some clickbait article. Jarv Is… was originally founded to play at an Icelandic festival founded by the great Sigur Ros. They meant the project to be an experiment in songwriting techniques, trying to harness the power and energy of the live audience to fuel their creative fire. The live performance recordings eventually became the foundation of the album. Seems like a pretty successful experiment to me.
