Glay bassist Jiro became a fan of The Pillows during the Runners High tour in 1999 and became friends with their vocalist and guitarist Sawao Yamanaka.
In 2004, Jiro participated in the recording of The Pillows' 15th anniversary tribute album Synchronized Rockers, where he met Straightener drummer Shinpei Nakayama, saw his drumming style and thought he was talented.
Shinpei had asked to leave the group during the 2008 Shoot the Moon Tour, explaining that although he wanted to continue both bands, the stress was outweighing the joy.
[4] He was replaced by Ellegarden drummer Hirotaka Takahashi, whom Yamanaka asked to join after working together on his solo album.
[5] After another break, The Predators released the mini-album Monster in My Head on August 1, 2012, and supported it with a nationwide tour from September to October.
[7] The trio resumed activities in January 2018 with the release of "Arabian Dance", a single featuring four studio songs and five live tracks that was sold only through mail-order and at venues on its accompanying tour.
