Dragon Ash (????????, Doragon Ashu?) are a Japanese rock group led by rap mogul Kenji Furuya. They are an icon in Japan and were one of the first groups to popularize hip hop in Japan. They brought a western flavor to Japanese music and helped to turn rap music mainstream, with a mixture of reggae, rap, rap-rock, punk, Spanish, and R&B influences. Some of their best known songs include "Grateful Days", "Life Goes On", and "I Love Hip Hop". The group uses various samples, most notably from the famous American alternative rock group, The Smashing Pumpkins. These songs include "Cherub Rock", in which they sample the bass line from The Smashing Pumpkins song by the same name, and "Grateful Days" in which they sample the opening of "Today"; they also named the song "Siva" after the Pumpkins song.
