Never use a cruelty when a joke will do in its place

Is that record store a good place to find underground hip-hop? I ask because I have yet to find a place in the greater Seattle area that has any such as Latryx, The Coup, Dose One, Deep Puddle Dynamics, and other such hip-hop acts. If you can lead into the right direction to a store that actually has these such albums I would greatly appreciate it thank you for your time
