Andrew Martin at PopSense sums this one up best:

When The Ecstatic closes with the once questionable but truly brilliant “Casa Bey”, two things become devastatingly clear. First, few other albums in recent years are filled with such smooth transitions as this record. Each track flows into the next perfectly and makes it feel like an album and not just a collection of songs. Secondly, The Ecstatic feels like the album Mos has always wanted and intended to make. It’s experimental and progressive without being too left-field and isolating. It’s hip-hop without being a photocopy of what he’s released in the past. Simply put, it’s Mos being Mos: Equal parts oddball and genius, even with his flaws. Full Review
