Narrative:
EICAS; airspeed disagree and altitude disagree during climb out. Ran QRH and established reliable instruments and selected alternate on first officer's airdata and with maintenance control and dispatch concurrence continued. Later on during climb EICAS; rudder ratio and aileron lockout. Ran QRH and then developed an (unidentifiable) aerodynamic rumble and elected to return to ZZZ and request priority handling in the interest of safety.
