David Jolicoeur, best known as the rapper Trugoy the Dove of the climate-shifting rap group De La Soul, weathered decades of industry shifts with acerbic wit, oblique rhyme styles and intense bouts of self-reflection that flew in the face of hip-hop’s boast-centric bottom line.

Jolicoeur, also known as “Plug Two” in the Long Island trio he helped found in 1988 with Kelvin Mercer (Posdnuos) and Vincent Mason (P.A. Pasemaster Mase) died on Sunday at 54, just weeks before the group’s songs, long absent from streaming services, will finally arrive on digital platforms.

De La Soul’s debut album, “3 Feet High and Rising,” from 1989, was nothing short of a sea change moment in the genre’s sound, fashion, attitude and aesthetic. As leading lights of the Native Tongues collective — a loose crew of fellow travelers that included Jungle Brothers, A Tribe Called Quest, Queen Latifah and Monie Love — De La’s baggy bohemian look would replace rap’s thick gold chains and sweatsuits with Afrocentric leather medallions and vintage patterns. It was Jolicoeur’s innovation to raid their dads’ closets for bell bottoms and straighten the legs, not to mention stylizing their asymmetrical haircuts.

De La Soul broke the Top 40 that year with the pop splash “Me, Myself and I” — for years the trio would reliably add “We hate this song!” when performing it live — but went on to become hip-hop royalty thanks to the emotional depth plumbed in tunes like “Tread Water” and “I Am I Be.”
