Brazil has bred a lot of bands through the years. With a band-history that begins in 2001 Justabeli is among the more established groups. The trio plays death metal just like how it sounded in the mid-eighties. It sounds like the Brazilians are heavily inspired by Kreator, Sodom and Death to name three.
As you probably have figured by now there's nothing revolutionary in Justabeli's music. I also doubt this was their intention to begin with. The songs are decent, but lacks a bit of catchiness. It doesn't make things any better that the music suffers a lot under a rather thin and muddy production. For the same reason the songs don't sound very tight and most of the reason for this obviously lies in the production, but the songs themselves also misses 'that extra something' that would make them stand out. I'm sure with some work and progression the trio can find a label at some point, but I doubt this demo will make the difference.
