A 61-T pulsed magnetic field suppresses superconductivity in La2-xSrxCuO4 single crystals and reveals an insulator-to-metal (IM) crossover for both in-plane resistivity rho(ab) and c-axis resistivity rho(c) at a Sr concentration near optimum doping (x similar or equal to 0.16). The IM transition is unusual in that all underdoped samples (x < 0.16) show low-temperature insulating behavior, even in samples with linear-T rho(ab) above T-c and apparently large k(F)l.
