Milwaukee bred sisters, Monique (Vocals, Cello) and Chauntee Ross (Vocals, Violin), spent their entire music education not quite fitting any particular mold. Raised by two ministers, enrolled in conservatory at young ages, Monique and Chauntee embraced what made them different. Their art is meant to reflect their varying musical interests in a way that draws the listener in. Music becomes a journey and SistaStrings invites you to find your path.

Collaboration has been at the forefront of SistaStrings’ art. The sisters grew up playing their instruments in the church which is where their love of harmonies and improvisation was cultivated. Their entire childhood was immersed in music and making music with their peers in many different settings. It wasn’t until 2014 when both Monique and Chauntee moved back to their hometown, Milwaukee, WI when they began this project. They began exploring their sound as SistaStrings and collaborating with a variety of Milwaukee artist and found a strong creative community.


During their “discovery phase”, SistaStrings met and began to collaborate with fellow Milwaukeean Peter Mulvey. They’ve recorded two albums together. 2021 opened a new chapter for the duo as they relocated to Nashville. They have participated as members of The Rainbow Coalition of the Loving, Allison Russell’s touring band. Monique and Chauntee are currently touring with Brandi Carlile. It’s no coincidence that collaboration is a strong point for the sisters. They believe that music and the arts reflect life and use their music to create opportunity for others and promote love and acceptance.


“We grew up appreciating different genres from classical to gospel to soul to hip hop, our music is a criss-cross marriage of all sorts of genres to make it something truly our own. It’s music for the soul.”  

-Chauntee Ross, Interview with Rock the Green for Rock the Stream benefit concert series

Multi-instrumentalist producer/singer/rapper/songwriter from Milwaukee, WI, pulling from years of jazz saxophone study and music production to craft a unique blend of rap/jazz/soul. 


Klassik is as dexterous a rapper as he is an impassioned and soulful singer, often highlighted by his intense and incisive falsetto. All of this is intertwined with his own unique, personal and unbridled storytelling. With a penchant for curation and collaboration, which he likens to that of one of his biggest inspirations, Quincy Jones, Klassik’s production is crafted with intent, beauty and depth of musicality. 


Most recent album (QUIET, 2019) was named the #1 album of 2019 by the Milwaukee Journal Sentinel, and garnered awards for Best Solo Artist and Critic’s Choice for Album of the Year at the 2019 Radio Milwaukee Music Awards.


A true class act, Klassik works to stir the souls of listeners into action with empathy, passion, and purpose through his own self-reflective sonic art.


Kellen 'Klassik' Abston performed at Rock the Green's Sustainability Festival in 2016 & 2017


Born and raised in Milwaukee, grown in an environment where determination was a must to be developed, Jonah Denae is an up and coming female rapper/artist with a sound you don't necessarily hear from the music scene in the city. But still, catering to the influence. To the structure of pen, endless discography of lyricism and rhyme schemes and a flow intertwined with versatility,  Denae is a promising figure to bring back the feel of femcee hiphop that gives you a looksee of being rough around the edges and the realness of what can blossom within the cracks of the concrete. Poetry within her words. Rhythm within her lyrics.


"If I want it, i'ma get it. By any means necessary. Under no circumstance."  


This is, Jonah Denae
