Duos are a great choice when a little more music animation and visuals are needed for an event. Upright Bass and Piano creates a strong visual, is not too loud, and is a common jazz duo. Another great alternative is Piano and Vibes. It is another standard jazz duo for visual and controlled volume. Sax and Keys is a great duo for a more forefront approach. It's also a great alternative for events held outside. For those events where dancing may occur but the budget is tight, consider my Keys and Drums duo. This duo is a versatile combination. It can handle cocktails and dinner with light instrumentals and break out into dance music when I add vocals. Incidentally, vocals can be added with any combination.
