Blues rock started with rock musicians in the United Kingdom and the United States performing American blues songs. They typically recreated electric Chicago-style blues songs, such as those by Muddy Waters, Jimmy Reed, Howlin' Wolf, and Albert King, at faster tempos and with a more aggressive sound common to rock.
Vinegar-based condiments, such as mustard, relish and horseradish, keep for 12 months or until the expiration date in unopened jars in the pantry. An open mustard container can still keep for 12 months if you store it in the refrigerator, but it can spoil within one month if you keep it at room temperature. An open container of relish lasts six months refrigerated and should not be stored in the pantry.
Whole spices can be kept longer --- for up to about four years for unopened containers; less for opened ones. One of the best ways to tell if your spices and herbs are too old is to open the container and smell the contents. Weak or no aroma means tasteless food. Old spices and herbs do not add flavor to your food.
