i was actually think about that when i saw those videos your analysis is spot on
alain's group sounds very very mature and well balanced compared to most 'young groups"
yeah sometimes the chorus from fally's guys are like they are whispering(and same for fally himself)
one thing i also find funny in the groups is the way they do their impros(its blatant in very recent groups),you'd think they did lyrics together very very basics
we have less and less guys like montana kamenga who always create vocal with a deep message and matching the lyrics of the song well
