 For their fifth album (1987's "Social Responsibility"), the band was still a duo of Rouse and Bergman, with Rouse performing all instruments except bass.The band expanded to a quintet for a subsequent tour, and for their final studio release, 1988's "Against All Flags", Tirez Tirez's line-up consisted of Rouse (vocals/guitar), Bergman (bass), and new members Bill Tesar (drums), Rave Tesar (keyboards) and Mark Lampariello (guitar).According to Mikel Rouse's web site, one further Tirez Tirez album was recorded after 1988, but it was never released.
