We calculate the spectrum of a two dimensional CFT on a cylinder, perturbedby a general linear combination of $T\bar{T}$, $J\bar{T}$ and $T\bar{J}$, byutilizing the relation of this problem to certain solvable single tracecurrent-current deformations of the worldsheet theory of strings on $AdS_3$. Weshow that this spectrum is well behaved (i.e. the energies are real) if andonly if the dual bulk geometry is well behaved (i.e. the signature of the bulkspacetime is $(1,2)$ and there are no closed timelike curves). We also commenton the relations of string theory on $AdS_3$ and its deformations to symmetricproduct CFT's, matrix string theory, and a black hole description of highlyexcited fundamental strings.
