Julian Lage may be the first artist I’ve seen in concert, and wanted to see again the next night simply because I needed more time to comprehend what I had witnessed. Usually, as a guitarist, when I hear something on guitar, I have at least a rudimentary understanding of what’s going on. While I could never dream of playing it myself, I could at least imagine how it might be possible for someone to play. Not with Julian Lage. If a composer would have come to me with a transcription of what I heard Thursday night, I would have shook my head, and told them that their composition was impossible on guitar.
