When first approached to write a work for the Metropolitan Wind Symphony (Boston), American composer Greg Sanders tried to find out what unique qualities and characteristics were present in the makeup of the MWS organization. In his search he found a group of dedicated and sincere musical talents.

A promotional video about the MWS musical activities was sent to him in the early stages of the composition process. The video showed an energetic and eclectic group made up of performers of differing professions and backgrounds that drive form all points once a week to do one thing only: make music. It is to this group of dedicated musicians and their conductor David Martins that MeTro! is dedicated.

The Boston Public Transportation system or "T", as it is known by locals, plays an integral part in most Bostonians lives. MeTro! captures musically the energy and often sheer frenzy of living and working in a major metropolitan area.

In one continuous movement the work begins with a slow introduction, making use of what the composer refers to as "urban jazz" melodic and harmonic material. This opening section uses a number of solo winds interwoven into a complex collection of musical lines and harmonies. The introduction section is brought to a close by cascading arpeggiated lines and descending sonorities.

The Presto section is a cyclic collection of short motivic patterns that are juxtaposed with and against each other throughout the work in a flurry of activity. Even the softer more restrained sections have an underlying pulse of anticipation. This section works itself to a close in a cacophony of sound, with all the material presented in one final burst of energy. The work concludes with a short coda that makes use of transformed material from the slower opening section, bringing the work to a majestic close.
