Around 2000, Reynolds began writing a series of short, complementary solos, entitled, for example, "imagE/guitar" and "imAge/guitar." The “E” is more elegiac and evocative, the “A”, assertive and angular. As his interest in algorithmic transformation migrated towards real-time performance interaction, Reynolds produced two extended composition using the materials of a solo pair as his thematic resource. "Dream Mirror", for guitar and computer musician, is a duo whose internal sections are framed by completely notated music, but move into a collaboratively improvisational interaction within these frames.
