Yup, Quinn and his Done Deal Crew, JT and his Get Low associates and Mac Dre and the Thizz dudes are all cool.
One group that people don't often mention is Playa Jay Tee and the guys who appear on his 40 Ounce projects (Baby Beesh/Bash, Don Cisco, Frost, B-12, Young Dru, Johnny Z on the production, TL now that he's returned, Miami, and whoever else I missed). They seem like a cool bunch, IMHO, and their appearances on each other's CDs are very consistent.
PEACE!
