Live music website BAMM.tv has launched an iPad app, providing streaming access to its 70 hours of live performances and documentaries. The catalogue is skewed towards indie artists – Wallpaper, Geographer, The Stone Foxes, Mirah, Ana Tijoux and others – with the app designed to look like a virtual music venue “so authentic you can almost smell the stale beer in the air”. Which is nice. Users can create their own playlists (“playmixes”), read band biographies and blog posts, browse tour dates and share content with friends. In the latter case, sharing unlocks premium videos, live streams and ringtones. Initially, the business model is advertising, but with scope for in-app purchases in the future.
