Discogs has the album https://www.discogs.com/release/14484878 but only one group, Roadrunners, has any info available.
Who are all the others? I don’t know. WMP pulled the data from whatever database it uses so I’ll just have Picard sort the files with that. Not going to try tracking down info on a bunch of what’re probably one hit garage bands. 
You don’t have to flesh out every artist you add. You can just add them with the type “Group” and leave them at that, with a disambiguation (e.g. “punk rock band”) if necessary.
Brazilian bands can be tricky. I’ve had a couple of Bandcamp compilations with all kinds of odd names.
When adding new unknown bands like that I was popping “Brazilian” into some of the disambiguations to make them stand out from others which may get a similar name. I also try and copy\paste the discogs links across to link MB to Discogs. Any little crumb will help the next editor.
