Itâs true, Katy Perryâs most recent album, Prism, wasnât quite the neon-champagne-overflow heart-shaped piece of pop perfection that 2010âs Teenage Dream was, but Ms. Perryâs press release for the current Prismatic tourâcoming to a dome near youâconfirms: âThis colorful show will bring you all the songs you know as well as ones from my new album, Prism.â You hear that? COLORFUL SHOW! SONGS YOU KNOW! Photos of the tour so far confirm some pretty off-the-chain outfits (and a pyramid!), plus the poppier-than-ever sister duo Tegan and Sara are opening. Go forth and roar. (Tacoma Dome, 2727 East D St, Tacoma, tacomadome.org, 7:30 pm, $20.50â$100.50, all ages)
