Founded in November 2006 by Amaro Assad (guitar), Yves Pessanha (drums), Arthur Bernardez (vocals) and Lucio Almeida (bass), earlyer called by the name of Inner Strentgh. The first time that the band present themselves was in an event called "Rock à 5 Reais I" managed by Amaro Assad, the band had only one month of existence. By the begining of the year 2007, Bruno P. Soares had joined the band in adition for one more guitarist and at the same time the bassist Lucio Almeida had left. Soon after Lucio A. had left another bassist joined the group, named Jean, he didn't "fit in" and left a few weaks later. After that, Diego Carvalho took the place o bassist of the band, with this new formation, they changed the name to an easy one, Inner Side. The band participated of a lot of events like "Alterna Campos I e II", "Rock à 5 Reais II" and many others live shows around the town. By the begining of the year 2008 Arthur (vocals) had left the group, so that they had to make a new test for a new vocalist, Rodolfo Barreto was the one they choose, in may 2008, Inner Side participated of the "II Festival Underground" showing an huge upgrade, and got lots of comments saying that it was their best performance so far. Rodolfo left the band right after, with this, Diego Carvalho (bassist) took the place of new vocal, and so along with this whole change Lucio Almeida took back his place as bassist of the band. And so that is the last formation of the band. Inner Side starts to fix themselves into Metalcore, but never forgeting the influences seeing in some of their own songs.
