May Our Chambers Be Full is a collaborative studio album by American singer-songwriter Emma Ruth Rundle and doom metal band Thou.

[12] AllMusic's James Christopher Monger stated: "for all of its epic grandiosity, May Our Chambers Be Full only clocks in at a mere 37 minutes, but in doing so leaves a more indelible impression".

[7] Dafydd Jenkins of Loud and Quiet said: "The whole LP would be a great release for either artist, but it's the brilliant convergence of sensibilities that sets it apart in the landscape of alternative metal".

[10] Todd Dedman of Beats Per Minute said: "it's the document of two beloved alt-metal worlds colliding to head-shuddering effect; a record of skull crushing intensity in places, with merciless riffs conjured up from the deepest abyss, which are counterpoised with quiet, ethereal dark-folk introspection – a mix that shouldn't really work but absolutely does".

[8] Grayson Haver Currin of Pitchfork said: "However exhilarating its discrete peaks, May Our Chambers Be Full is one of those common collaborations that's more notable for what it says about those who made it than for the new material itself".
