Compton duo Problem and DJ Quik embark on a swaggering old-school odyssey on Rosecrans, and it’s a journey fuelled by plenty of L.A. gangsta boogie: The lazy, luxurious grooves of “Bad Azz” and the title track were made to soundtrack a drive with the top down through the city’s streets on a sunny day. Problem’s gruffer flow is a perfect foil for Quick’s slick rhymes throughout, and the latter shows off his beatmaking chops with the freaky funk and head-bobbin’ grooves of “European Vacation”.
