Katy's collection of Katy Perry hits is back. After her last album "Prism", which took her to the top of the charts four years ago, and the subsequent world tour, album number five is coming. "Witness" is the title of the 15-song LP, a selection of about 40 songs the American singer wrote for it. Katy has already made the new album known with three singles, in which the singer receives active support: Skip Marley, hip-hoppers Migos and Nicki Minaj participate in the songs "Chained To The Rhythm", "Bon Appétit" and "Swish Swish". Like her predecessor, Katy Perry has enlisted a host of top songwriters and producers for "Witness", including Max Martin, Ali Payami, Sia, Jack Garratt, Hot Chip's Joe Goddard and many more. The result is a modern pop opus, a collection of hits. With "Witness", Katy Perry shows why she is one of the biggest pop stars and songwriters of our time.
