How John Luther Adams Became JLA

Adams asks for a different kind of listening. I heard the suggestion more than once that the most becoming presentation would have been simply a single concert devoted to Adams’ ocean and desert.
That brings up the major questions about Adams. Is his a music of enlightenment or escape? Is the attraction that of having sensations heightened or dulled, a dose of uppers for the ears, or downers? Is this for tuning in or chilling? The answers have to be personal and may not even be either/or.
