We have observed a massive reconstruction of the Fermi surface of single crystal chromium as a function of high pressure and high magnetic fields, with multiple new orbits appearing above 0.93 GPa. Additionally, some orbits have field-induced effective masses of ~0.06-0.07 me, seen only at high magnetic fields. Based on the temperature insensitivity displayed by the oscillation amplitudes at these frequencies, we attribute the orbits to quantum interference rather than Landau quantization.
