The document describes a research project called Location33 that explores new types of mobile music experiences. It involves creating a musical album where listeners can explore songs and stories by walking around downtown Culver City and approaching location-based "nodes" that play different musical fragments. The goal is to make the album experience more interactive by allowing listeners to actively participate in assembling the album based on their movement through physical space. It discusses prior related work, the project description and goals, implementation details, and conclusions.
