CAMBRIDGE -- Collage New Music closed its season Monday night with four works composed for the group, three of them world premieres. The Collage instrumentalists and guests performed all four with their usual expertise, and David Hoose conducted with clarity and conviction.
Tod Machover's ''Another Life" supplements live instrumentalists with electronics. The live instruments dominate; the electronics add atmosphere and reinforcement. Much of the work of MIT's Media Lab guru in the last decade has centered on exploration and experimentation, or on enabling others to express themselves. This piece revisits some of the musical concerns of his own youth with the resources and experience of maturity; it is about personal expression, full of exuberance and regret, nostalgia and celebration.
