CREATE TABLE table_204_128 (id DECIMAL, "region" TEXT, "date" TEXT, "label" TEXT, "format" TEXT, "catalog" TEXT)

in how many countries was the album released before 1990 ?
SELECT COUNT(DISTINCT ("region")) FROM table_204_128 WHERE "date" < 1990
SELECT COUNT(DISTINCT "region") FROM "table_204_128" WHERE "date" < 1990
