The new KISS collaboration with Japanese group Momoiro Clover Z, Samurai Son, is out now to buy on iTunes for 99p. It hasn't been to everyone's taste, but it is a grower and is also being added to the set list for the imminent Japanese tour. The song is also available on the KISS 40 compilation as well as the KISS version of the CD single, which also includes a version of Rock & Roll All Nite by Momoiro Clover Z.
