Batwanger featured Tony Infantino on drums & vocals, and J.M.Smig on guitar & vocals.
J.M. has made some of the Batwanger rehearsals available through Bandcamp stating :
Batwanger was a guitar/drum duo (with occasional third parties) from the North Shore of Massachusetts that existed years before (and played better than) the White Stripes. This catalog is compiled from rehearsals and jam sessions recorded 1988-1992.
