Here's another practice loop, this time for frevo. It's a snippet of the SpokFrevo Orquestra, who are the premier modern frevo group out of Recife, and likely the world. If you want you frevo to swing properly, these are the guys to check out.
You can, and should, play what you hear on the recording, but also be sure to re-visit the post on frevo for some different orchestration ideas to try. E-mail me for a PDF.
