I would avoid a collection of harpsichord by Bach with a title like Musical Offering. I don't remember the exact title, but it is quite possibly the worst rendition of Bach since I started learning to play piano at age 8 with a book of simplified Bach melodies. The harpsichordist in particular has no clue about rhythm or tempo and sort of randomly speeds up and slows down. I don't know how it got recorded.

I am the Doctor, and THIS... is my SPOON!
