Roku expanded its channel selection Thursday with the addition of full-length HD concerts and music documentaries from Qello Concerts.

Roku said the Qello Concerts channel offers unlimited access to thousands of hours of concerts and documentaries, including The Rolling Stones' Live at the Max and Lady Gaga's The Monster Ball Tour: Live at Madison Square Garden, and features performances from other artists such as Jimi Hendrix, Beyoncé, Jay-Z, Eric Clapton, B.B. King, Plácido Domingo, Queen, Imagine Dragons, Nirvana, Mumford & Sons, My Morning Jacket, TobyMac, and Barbra Streisand.

Roku users who are new to the service can sign up for a seven-day free trial.

Roku said the Qello Concerts channel is offered on all current-generation players, including the new $49.99 Roku Streaming Stick (HDMI) version.

Roku, the subject of recent IPO rumors, has shipped about 8 million devices in the U.S., but has yet to release international shipment figures.
