No time for rest in Godspeed’s Montreal enclave, as the collective’s myriad spin-offs continue to fight the capitalist hegemony with sad tunes and very long titles. Mt Zion are ostensibly the pop wing, adding vocals from guitarist Efrim and?new here?a massed choir to the usual thicket of slow guitars and chamber strings. It’s debatable how necessary his croak is, since Godspeed’s great gift is to disseminate radical politics by musical implication rather than explicit polemic. Nevertheless, this remains marvellous music:at once complex and direct; unfashionably serious; uncommonly moving.
