It's Steve Jones (Sex Pistols) Matt Sorum and Duff McKagan (Guns N' Roses) and John Taylor (Duran Duran) together, having fun. Vocals are shared among the members. The drums are heavy-handed but impressive.
It occasionally sounds like Nirvana minus the grunge production, or Sex Pistols minus the essential attitude. In short, it's rock n roll with power-punk overtones.
