Let's forget that Saroos is a closed, three-minded system: a fixed and fully committed entity of three. Known to reinvent themselves in less drastic ways, Christoph Brandner, Max Punktezahl, and Florian Zimmer, have opened the floodgates to collaboration on their quietly explosive latest album Turtle Roll. Announced by 2021 singles "Tin & Glass" featuring Ronald Lippok and aptly titled "Frequency Change" featuring Leila Gharib aka Sequoyah Tiger, the sixth full-length sees the Berlin threesome add another handful of vocal guests along the way. Kicked off by the motoric B-funk (Berlin represent) of the Lippok-assisted "Tin & Glass," complete with retro-futuristic effects, spoken declarations, and non-terrestrial vibes, it might not be Daft Punk playing at their house, but a byobv (vibe) house party of musical minds isn't too far off, actually! Once again as much a mixtape as an album, the mood, vibe, and color changes with every new collaborative tune: From ethereally soothing and dreamy ("The Mind Knows" featuring Solent from Canada) to clap-driven and wildly hypnotic (that pounding "Mutazione," featuring vocals and rhymes courtesy of Eva Geist from Italy) and almost radio-ready when that stadium-sized oomph of "Frequency Change" featuring Sequoyah Tiger arrives around halfway in. Elsewhere, Japanese guest Kiki Hitomi (WaqWaq Kingdom) adds exotic ecstasy to the hypothermic beatscapes of "The Sign," while Ukrainian vocalist Lucy Zoria pushes poetic layers over "Southern Blue"'s wonky foundation that hardens and finds more direction with each round the beat clock takes -- until it's impossible to escape that undertow. "My baby makes it better," sings Caleb Dailey on the faithful and still-loving "Being with You," a sepia, softly churning look back by the US songsmith, a sweetly shimmering ode to a relationship. Speaking of foursomes, there's four instrumental tracks scattered throughout the new LP -- ranging from a painting in crystal clear colors of night ("Organ of Recall") to the highly dramatic sonic tapestry of "Thicket" (with vocals as well). Before the perfect goodbye of slow-moving album closer "Here Before," "Passed Out" sounds like Odd Nosdam finding his feet after blacking out on a German carnival. Titled after a surf maneuver that allows you to break through the crests on the way out, Saroos have skipped the obvious waves with Turtle Roll -- creating their own kind of sonic "Hang Ten" by adding seven new voices to the mix.
