Query: it has substance but no good vocals

nina sky is a weired combination of good subject matter with horrible vocales.the song about their dead friend was good but like i said they really cant sing. they can carry a tune but thats it.the production on this cd was unique and different though.but it has nothing to offer as far as singing talent.the only nail in the coffin for this album is the fact that they can't sing.but if they could this would be a 4 star album easily
