Razorback is a Filipino hard rock band formed in 1990. Originally known for being regulars at the now-defunct Kalye, a club in Makati, the band has performed at full-scale concerts and opened for Silverchair, Rage Against the Machine and Metallica. Razorback first began performing covers of legendary rockers such as Led Zeppelin and Juan De la Cruz Band, Black Sabbath and Iron Maiden. The group was put together by drummer Miguel Ortigas and guitarists Tirso Ripoll and David Aguirre. Members of Razorback and Wolfgang used to jam onstage billed as the Flaming Hemorrhoids. Five years later, the band, original vocalist Jose Mari Cuervo was replaced by Kevin Roy on vocals, alongside Ripoll and Aguirre on guitars, Ortigas on drums and Louie Talan on bass, released their debut album entitled "Hebigat Sounds Volume One". (Hebigat is a portmanteau, created by fusing the words Hebi, a play on the English word heavy, and the Filipino word bigat, literally, heavy.) The album contained such tracks as "Giyang", "Tabi ng Bulkan (Beside the Volcano)" and "Pepe D' Hepe". David Aguirre is now the lead guitarist for the Southern California-based band 3 Headed Dog. Manuel Legarda, also of Wolfgang, has taken over his guitar duties for Razorback. In 2002, the band embarked on an ambitious project - an eponymously-titled double CD album. Razorback dispelled rumours that this is their final album, much to the relief of fans who have been on the receiving end of this anxiety-inducing piece of false information. The album starts out with "Minsan Lang (Not Often)". Diversity is evident, with songs ranging from classic rock, ("Minsan Lang", "Wakasan (End It)", "Dagat ng Pag-asa (Sea of Hope)"), to Pink Floydesque tracks ("Puerto Jam", "Earthen Drum") and acoustic love songs ("Ditty", "Sixteen Days").
