[Machine Translation] Beck himself has selected and released an album of rare tracks from the B-sides (C/W) of the singles he has released so far at a special price! Since his debut, Beck has cut many singles, some of which have never been released in Japan, and many of which are difficult to find. This album will contain 8 rare tracks selected from those many B-side songs. This will be a Japan-only release, with a serial number. Includes a serial number and a postcard for applying for a T-shirt autographed by Beck, which is a special offer in conjunction with the mini album to be released on April 19.
