aside from some of the more obvious choices (rushdie, wallace, mccarthy, morrison):

don delillo, esp. underworld and white noise

ted chiang, esp. exhalation

marilyn robinson, esp. housekeeping

denis johnson, esp. jesus' son and tree of smoke

colson whitehead, esp. the intuitionist and the nickel boys

and while relatively new so maybe not at the same status as some other writers, jamil jan kochai and nana kwame adjei-brenyah will be making lists like these in the future if they keep writing the way they have.
