RTJ Cu4tro highlights some of the more exciting Latinx artists working in the margins, but it doesn’t really work as a coherent album. With wildly different sounds, the sequence doesn’t have the same flow as the original project; it’s as if one attempted to reassemble a puzzle in the same way, even after all the pieces changed shape. Since the only connective tissue outside of the original material is the amorphous “Latin” category—a commerce-driven catch-all that places often disparate genres under the same umbrella—that inconsistency is somewhat inevitable. It’s the rare Run the Jewels project in which the sum of its parts exceeds the whole.
