Tim Mangan takes a look at the offerings in Orange County’s upcoming season and notes that, “for the most part, the new music that is being played isn’t all that challenging (not that it has to be). But there is, and always has been, a huge lacuna in the modern repertoire that is performed here in O.C., and it makes it difficult for listeners to hear any new music with a perspective that will allow them to comprehend it or place it in some sort of historical continuum.”
