Shane Valle is the tenor saxophonist for the Portland Wind Symphony and the Portland-based Quartet 321. His mother’s affinity for Kenny G put a saxophone in Shane’s hands at age 9, though Shane has taken his musical inspiration from elsewhere, namely modern and late- romantic classical music. Shane’s most formative musical experiences were at the University of Washington where a supportive Director of Concert Bands provided many opportunities for Shane to experience playing as a soloist, chamber musician, and large ensemble member at a very high level. Shane’s day job is as a Transportation Planner for the City of Portland, working to make it safer and easier to get around town.
