Almost all early Wimpshake material was on Slampt. Their web presence is at the slampt underground organization, but sadly that label is no longer releasing new music.
Thanks to Radio Shack and mobile emotions, the 1st MW tape and all their 7"s are now online in mp3 form. They are otherwise impossible to find.
Shout out to technology!
At this writing, there are still THE WIMP records at troubleman and copies of the comps with Wimpshake contributions. If you are looking for something else, try these mailorder thingies, or google your way around. If you have no luck, try entering "whimpshake" as an alternate spelling. Tell me if you know about a distributor that's not listed here:
