For me, Abacab is the most important album of the band.
I'd like to push back against that actually, not because Abacab isn't an important album, it certainly is, in terms of importance though, I don't think it can be compared to the sense of uncertainty stemming from the lead singer's departure with the whole press basically delivering the band's eulogy, those who were around will remember that or even when the acknowledged driving force within the group leaves, leaving a bunch of semi-professional lads unsure as whether to continue or less. Trespass and Trick are certainly as pivotal as Abacab for the band, probably more in my view and I try not to be swayed by the fact that I actually like those albums, it's purely on the merits of importance. I will, however, say that Abacab, contrary to the other 2 albums, where they had to react to a situation of possible unraveling, was a conscious, voluntary choice to change things radically and although I don't rate the album very highly, I respect that.
