Hip-hop may have capable artists like Stones Throw's Jonwayne ready to take the genre in new directions, but the vets continue to show that they still have important contributions to make. Stones Throw alum Dudley Perkins is releasing his first solo album in 4 years, Dr. Stokley, next week. On his second single, the Georgia Anne Muldrow produced "Hearing Test", the Cali emcee spews venomous verses about his passion for the culture. Legendary Bronx rapper Percee P goes first, laying tongue-twisters in his signature flow to devastating effect and reminding me that I have to go back and listen to Perseverance. Complete with scratched vocal snippets, this track is one for the purists to salivate over. You can expect more head nodders from Dudley's wife Georgia as well as from the one and only Madlib when Dr. Stokley drops on Black Friday.
