In the past five years, the members of Oi-Ster have journeyed into their own separate lives.
The beginning of the band cannot be really determined, for each one of them had various beginnings in the realms of music. Rum had started playing guitars at the age of twelve. Finding his own style, rhythm, and with influences of some great guitarist in the history, such as Jimi Hendrix, Dimebag Darrell, Jimmy Page, and Zak Wylde, through the years he successfully master the craft of guitars.
Rum entered Don Hilarion G. Gonzaga Memorial High School, Talisay City, Negros Occidental. He was misunderstood by his teachers because of his passion with the punk culture. He draws Gothic arts, listens to metal sounds, and doesn’t confirm with the rules as a punk rocker. It was during his third year in high school when he met Mario. The two shared the same passion in music and simultaneously became close friends. They decided to form a band but failed to perform in school because of some oppressors.
On the other hand, Rhod and Barley were brothers and first cousins of Bertrum. They have their own distinct style when it comes to music approach. At first, Barley was hooked with Classical Rhythm and Blues while Rhod is in with Alternative music. They both learn how to play guitars during high school, on their own. With influences of some great Alternative bands, such as Incubus, Sound Garden, Rage Against the Machine, Third Eye Blind, Travis, Oasis, The Corrs, U2, Audioslave, Smashing Pumpkins, REM, and Nirvana, they evolved into something different, raw, unsaturated. But the two got bored with the alternative because it became a pop sensation. In their point of view, pop is idiotic!
Through the years Rhod and Barley became more mature when it comes to music approaches. From alternative sound, they switch to thrash, black, and death metal. But they are not satisfied; they experimented with the Punk Culture and became pioneers in Filipino Punk Metal.
During the summer of 2005, the four gathered together and definite to form a band. They try to make their own distinct sound; days of experimenting and listening to the Ramones, Exploited, Casualties, Black Sabbath, Red Hot Chili Peppers, Megadeath, Pantera, Wolfgang, Kreator, had resulted into a punk sound but different from the ordinary and classical. With metal music as a major influence, their hardship had resulted into a sound that is more radical and novel – Punk Metal.
Rhod, Rum, Mario, and Barley have suffered from oppressors of the society and often misunderstood. And they met so many problems and confusions along the way, and one of them is naming the band. It was during a sleepover, which the four decided to a certain name that would identify their style, culture, and music. They discuss so many titles, like; Berlin Wall, Tempura, Twisted Poets, Twisted Angels, etc. And hours had passed but decided on nothing, completely nothing.
A day after the sleepover, Rum was approached by a friend Azif in which he was informed regarding the gathering of all bands in the metro. Rum was undecided but enlisted the band under the name – Oi-Ster.
They continue their maturation in music approaches and definitely got their premiere event last July of 2006 at a certain resto bar along Lizares Avenue, Bacolod City. From that point, all together they became the pioneer in Filipino Punk Metal.
