Sign – Naruto Cover by Shibuya Sunrise Ever thought you’d hear a 1950’s Doo Wop version of a Naruto song? Shibuya Sunrise’s English cover of Sign by FLOW is very different to the rock original but we love it. Formed in 1998, Flow are a 5-piece Japanese rock band who have made waves in the anime scene, their songs featuring in a number of well known series. With 29 singles and 9 studio albums under their belt, we can only hope that we’ve done them and their renowned song justice. The song is available on Spotify now.
