Vaselina 1985 Hit: Sem

When “Sem Vaselina” started popping up at bailes (funk parties) in Rio de Janeiro’s suburbs, authorities were horrified. This wasn’t the polished, romantic MPB or the safe pop-rock of the era. This was sexually explicit, repetitive, and aimed directly at the working-class youth.

At its core, “Sem Vaselina” is a high-energy, electro-funk track credited to Deise do性感 (Deise the Sexy) or sometimes simply listed as an anonymous “Funk Melody” production. The music was built on a heavy, repetitive Miami bass beat—the same 808-heavy sound that was dominating dance floors in the US with artists like 2 Live Crew.

The song was . Record stores refused to sell it. But that only made it more popular. Bootleg copies on cassette tapes spread like wildfire. The Miami Bass Connection “Sem Vaselina” is a perfect example of Brazil’s Funk Carioca (Rio Funk) in its infancy.
