If ExceptionB is derived from ExceptionA then both samples will work in the same way

In the second example, you will only catch exceptions of type ExceptionA and anything derived from it. So, if ExceptionB is derived from ExceptionA this will work, if not you'll only catch one of the exceptions.

To catch them seperately, the catch blocks have to be switched.

or do I still need to use a Graphics object, just to composite my text onto my background?

using (Bitmap newAlbumArt = new Bitmap(width, height, PixelFormats.Format24bppRgb))

    using (Graphics gfx = Graphics.FromImage(newAlbumArt))
