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.
Most sources say that home-canned foods will store safely for at least one year. With other food items, the level of acid in the food is the critical element for determining how long it may store. Low-acid foods last longer on your shelves than foods with higher amounts of acid. Some sources say all commercially canned food should last at least two years. Surprising to some, canned meats can last the longest. Most sources say they will keep for 2 to 5 years. Some sources say they will last even longer. I found a shocking story about a can of meat that was 118 years old.
