Rench, who had previously made a name for himself as an in-demand Brooklyn country and hip-hop producer and singer/songwriter, has toured the country with bluegrass pickers and hip-hop emcees to the delight of standing room crowds. Making beats for local NYC rappers and hosting country music nights in popular NYC venues, he had a musical itch that needed to be scratched and couldn’t help imagining what classic bluegrass would sound like with rap vocals and beats. The result was a genre-demolishing blitz that he put up for free. Hundreds of thousands of downloads followed creating an intense underground buzz. When FX Network came to Rench looking for the Gangstagrass sound for the theme song to their new series Justified, he had bluegrass players lay down an original track with rapper T.O.N.E-z, the younger brother of early hip-hop legends Special K and T-LaRoc. The result was “Long Hard Times To Come,” the song that opened every episode of six seasons of the hit series and was nominated for an Emmy Award in 2010. The same live bluegrass band approach was used to make Lightning On The Strings, Thunder On The Mic. Gangstagrass breaks new ground with original cuts and folk anthems. Their 2019 Live Album Pocket Full Of Fire spent 20 weeks in the top 10 Billboard bluegrass charts. With two emcees R-Son and Dolio The Sleuth trading verses, Dan Whitener on Banjo, Brian Farrow on Fiddle, and Rench on guitar, and frequent 3 part harmonies, the Gangstagrass live show has garnered a reputation among fans for its dynamism and spontaneity.
