Now this was tough. To the point where I voted and instantly regretted not voting for No Self Control!
In album order,
Intruder because it is PG at his creepy, unconventional best, whilst sounding magnificent. Holy cow, those drums.
Family Snapshot - great narrative (we can still argue about what it means), different sections, wonderful ending. Perhaps a bit of a forgotten gem
Biko - because you have to. I know it has been heard and played a million times at this point but I can still remember the first time I ever heard it. It would be a shame to let the over familiarity obscure the fact that it is magnificent, daring, fairly groundbreaking at the time, important, anthemic. You name it.
