Have a current-gen Roku device? Want to watch Lady Gaga's Monster Ball Tour performance from Madison Square Garden? Well, you're in luck. The aforementioned streaming gadgets in the US, Canada and the UK are getting a Qello Concerts channel today, bringing access to "the world's largest collection" of full-length performance and music documentaries via a $4.99 monthly All-Access Pass. While the added cost may be a bummer, live music enthusiasts can expect selections from Mumford & Sons, Queen, Wu-Tang Clan, Wolfmother and many more. If you don't already have a Qello subscription, you can try it out free for a week on that Roku box or streaming stick.
