I also think Fabio did a great job (as did Rafael!). The man is a total professional no matter which band has him holding the mic. I think if there's any reason why there are any detractors in this thread, it's that the songs are tuned down, presumably because that's how they were playing these songs to suit Edu's voice in the last days of his tenure with the band. I think that these songs would have sounded absolutely flawless had they been played in their standard tunings. Anyway, I am not against future shows with this lineup.
Stay metal. Never rust.
