Bad in its slang sense “excellent, first-rate” is surprisingly old, first appearing in print in the 1890s. It was then popularized in the 1920s within the jazz scene, and is typically associated with Black English. The slang sense “very tough, formidable” also appeared in the 19th century; it often meant “formidably skilled,” which ties in with the “excellent, first-rate” meaning.
