de Haas{endash}van Alphen measurements are reported in the organic metal {kappa}-(BEDT-TSF){sub 2}Cu[N(CN){sub 2}]Br, which is the structural analog of the highest T{sub c} (BEDT-TTF) salt. The frequencies are consistent with the calculated Fermi surface in the complete magnetic breakdown regime, with the warped structure manifesting itself as beats in the oscillations. Above the final node at {approximately}38.5T, the oscillations become characteristic of a two-dimensional metal. {copyright} {ital 1997} {ital The American Physical Society}
