Mannhai formed in 1999 with guitarist Ilkka Laaksomaa, bassist Oppu Laine, drummer, Junior Pietinen and ex-Xysma frontman Joanitor Muurinen. This debut album "The Sons Of Yesterday's Black Grouse" was recorded in Helsinki and has come to be regarded as one of the best stoner rock debuts of the new century. The opening track "Gazers Of The Red-Hot Stones" sets off with a stunning riff and the band never lets the excitement, tension and power flag for a second.
