Substance810 & Observe Since ’98* – The Lion’s Share 4: The Last Specimen LP

Underground hip-hop’s most imaginative saga roars back to life.

Since 2023, The Lion’s Share series has carved out a legacy in the depths of the underground—melding cinematic world-building with razor-sharp lyricism and gritty, soul-twisting production. The dynamic duo behind it all—Michigan emcee Substance810 and Wisconsin-based producer Observe Since ’98—have steadily redefined what conceptual rap can look and feel like. With nearly 3 million Spotify streams across Parts 1, 2, and 3, the numbers reflect what the culture already knows: this series is a landmark.
