The Last.TV offering will be available both online and offline, although initially it will be available via the main Last.fm site.
Last.fm was acquired by US media company CBS two years ago for $280m (?171m) and this move into TV is its latest strategy to reposition and build the Last.fm brand globally.
The initial TV offering will be based around music festivals in Europe - either through building bespoke events or partnering with existing festivals.
Last.TV is expected to launch in January. Parent company CBS is currently lining up sponsors and the service is also expected to incorporate both pre- and post-roll video ads.
