Season 2 has been out for a few years now and there's a movie currently out too but not yet translated I believe. গুগুল অথবা Ask would have shown আপনি that but anyways আপনি can watch it on watchanimeon.com All of the episodes are there plus the Extras and OVAs for both seasons. It will be under K-ON!! (<---two exclamation marks) in the K section I believe.
