Some of Hip-Hop’s greatest MCs have earned their place by sometimes rhyming slow, and sometimes rhyming really, really fast. Artists such as Eminem, Jay Z, Big Daddy Kane, Andre 3000, and Kool G Rap are among the elites who can tear into a beat, and turn their mandibles into automatic weapons of words.

While Tech N9ne is a 1990s disciple who continues to reach a new zenith in the 2010s, Logic is a 26 year-old who upholds the tenants of choppin’. This month, a video surfaced of the two meeting backstage during Logic’s Incredible True Story Tour. In Kansas City, Missouri, the two chart-crushing MCs relate to each other in a way that few can understand as they bust down bars fast and slow, in demonstration.

Logic plays the Strange Music co-founder some new material that has the Mental Giant reacting strongly. They also discuss the value of making their music without studio effects that ease breath control. Then, Tech runs a clinic on why it’s as hard on stage, while truly delivering the words (as he illustrates). Logic then asks a question, shifting his flow into sixth gear—impressing the K.C. King.

Both crafty competitors, there appears to be some playful back-and-forth as they compare dopely didactic deliveries.

Props to DJ Booth for finding this.
