"For fans of the first season in particular, these 13 episodes will satisfy them and excite them for Collection 2. For those who’ve seen Season 2 on tv during it’s original run, they will be happy to know that the video and audio quality hasn’t suffered in the transfer and is still very good, with no obvious issues. The ability to swap between Japanese and English speaking audio tracks, practically on the fly, never goes unappreciated. For the guys out there, K-On!! may not be for you, however it is still a charming, although somewhat aimless, slice-of-life story. What really brought the release down, and will do for most anime releases unfortunately, is the common void left in the special features. However, K-On!! Season 2 Collection 1 is a must have for true fans, despite the absence of any real extras." (Anime, K-ON!! 2) 7/10
