It says a lot about Silent Alarm that Bloc Party actually found enough people interested to remix every single one of the tracks on it; if you haven't got that album yet, I would unconditionally recommend it. But is this worth a purchase? It's predictably a mixed bag, ranging from disappointing retreads (Ladytron's 'Like Eating Glass', Blackbox's 'Positive Tension') to the unlistenable (DFA 1979's 'Luno'). There are also, however, a number of real gems here that make the exercise worthwhile. Phones' take on 'Banquet' somehow sounds even more vital and disco-volatile than the original, whilst the ever-reliable Mogwai do a subtle "re-Planning" which is extraordinarily sinister. Best by far, however, is the Engineers remix of 'Blue Light'. The original is probably the weakest track on Silent Alarm; the version on display here aches with a yearning beauty that easily outstrips it. If your Bloc Party fanatic, it's fairly essential stuff; if you're just passing through, however, be sure to boot up a search for the highlights, it's well worth your trouble.
