Jamal Smith (aka 10-19 The Numberman) is one half of Parker & the Numberman, a hip-hop trio with Jack King and Brandon Zamudio. Their EP Early was nominated for Best Hip-Hop Album at the 2011 San Diego Music Awards. In August 2012, the band (now a duo) won a Best Hip-Hop Album SDMA.

1019 The Numberman went solo in 2014 with a 4-song cassette tape, the Natalie Rose EP. His album Solus Superstes won Best Hip-Hop or Rap Album at the 2018 San Diego Music Awards.

In 2021, he released new music with a new trip-hop quartet, 10-19 and the Numbermen, described as "a psychedelic outfit bent on exploring the outer edges of traditional rap music - stretching and bending its boom-bap boundaries into a surreal mix of rhyme, rhythm, and melody." The project paired him with multi-instrumentalists/producers Joel Kynan, Brian Scafidi, and Sean Burdeaux. Recorded that January and released on local It's Okay, I'm Crying Records, their debut EP, Spokes, was preceded by singles such as "Smooth Piss" (which also came with a music video) and "July 10th."
