A song like “stupid horse” begins with late-2000s Warped Tour excess and ends somewhere closer to Dr. Demento. One of the best songs here, “ xXXi_wud_nvrstøp_ÜXXx ,” opens up like the bridge-and-tunnel megaclub music of the mid-to-late 2000s — think Cascada, or Kim Sozzi — and is soon jolted by a dubstep drop as tough as anything Skrillex ever made. The opening seconds of “I Need Help Immediately” may well be a nod to Cali Swag District’s “Teach Me How to Dougie,” a viral rap hit of 2010.

Image “1000 gecs” is the debut album by 100 gecs, following a self-titled EP.

100 gecs is a duo, Dylan Brady and Laura Les, who met in the D.I.Y. electronic-pop scene in St. Louis. (Les now lives in Chicago, and Brady lives in Los Angeles and collaborates with Diplo, among others, as a producer.) This is the second 100 gecs release, following a self-titled EP from 2016 that was more rigorous and less ambitious than the new album.

Historically, musicians who specialize in unlikely collisions — any iteration of rap-rock, or country-rap, for example — are often maligned, as if their alchemy were the stuff of confusion, not intention. But the warp-speed juxtapositions that 100 gecs deploys move their music past hybrid into something genuinely recombinant.

And also exhilarating — these songs pulse with joy and vitality. If anything, the collision of sounds is a distraction from the fact that “1000 gecs” is, at its core, an astonishingly sweet album. All the vocals are run through intense layers of processing, landing anywhere from chipmunk house to grindcore. Les, especially, writes vividly and petulantly about spineless partners. On “800db cloud,” she squeals, “I might go and throw my phone into the lake, yeah/It ain’t hard to quit caring what you think , yeah .” And on “money machine” — the video for which helped spur a recent burst of attention to 100 gecs — she’s shouting but it’s hard to feel mad.
