Probot had Dave Grohl as a drummer.
 He came up with "my wish list of all of my favorite singers from this era which is '82 to '89 underground metal, and all the bands I listened to at the time: Eric Wagner from Trouble, Snake from Voivod, Cronos [from Venom], Lemmy and Wino," and started contacting the musicians, some of whom were reached by Grohl's friend Matt Sweeney given the Foo Fighters had restarted their tour
Grohl also approached death metal legend Chuck Schuldiner of Death to contribute to Probot
