It seems to me that, to an extent, the band isn't really focused on being a 'performing' band. The Rhythm guitarist and Lead come to that, are acting more as if it's a bit of a 'jammimg' band or social meet up kind of thing? Maybe your objectives for the band and their's don't align? To be honest, any band that has been rehearsing for going on 2 years without a gig says to me that gigging is not their priority.
