This Borloo/Perth fivesome have been making waves Down Under since their debut 2018 EP, Repel, with a stack of press coverage, a sold-out national tour of Oz and a nomination for Album of the Year at the Western Australian Music Awards 2019. Their first seven- track collection surfed the post-Snarky Puppy/Hiatus Kaiyote wave of live electro-fusion favouring dreamy electronica and coffee-table-friendly EDM, with some on-trend Afrobeat flourishes.

Now comes the follow-up, Cascades, and it's a sizeable leap forward in ambition, as the Grievous crew show how, with deft sonic sleight of hand, and added heft to their beats (from the excellent Alex Reid), they can sound like a much larger, more powerful ensemble.

This is evident from the slinky Weather Report-infused opener, ‘Yawp’, with its lazy ‘River People’-style lope, Josiah Padmanabham's and Thomas Manson's respective guitar and keys overlapping in joyously complementary waves, under which Zac Grafton deploys a sumptuous synth bass to let the lead voice of Matthew McGlynn's trumpet soar above. Louis Cole's Knower are another stylistic touchstone with ‘Cloudbusting’'s jerky staccato sub-octave melody again placing complex emphasis below the becalmed surface of these tunes.

And while their debut felt like a lo-fi box-ticking exercise, here the soft embrace of the title track's rippling puddles of analogue keys and another bottomless synth bass throb, all lift McGlynn's Harmon-muted horn. Soon rising from the depths into a heart-tugging symphony of sound, this track wouldn’t sound out of place on a Jaga Jazzist set. Becalmed perhaps, but exciting too: GBC are a glorious assault on the senses.
