prior to joining thaeme & thiago, bertoldo had been part of grupo tradição alongside jefferson villalva, wagner pecóis, leandro azevedo, leonardo bertoldo and márcio adão pereira, from 2008 onwards, replacing the hugely popular michel teló on lead vocals. teló, lead vocals for the band had left to pursue a solo career after eleven years in the band (1997-2008). transition had been smooth as teló clearly explained that it was an amicable decision with no enmity or hard feelings. but bertoldo couldn't enjoy a similar popularity and soon band members started quitting before the folding of the band.
