With so many electro-pop groups on the current music scene it's possible to believe that there are more 80s-influenced bands nowadays than there were originally. Jumping on this particular bandwagon are Ladytron. On the evidence of their instrumentals it appears that Kraftwerk's 'The Robots' is their template of choice and using their arsenal of analog synthesizers they successfully reproduce - and sometimes develop on - that basic sound. Their best work invariably features the dual vocalists Helen and Mira who add the required air of clearly-enunciated but unemotional vocals. On a strong first half to the album they reach for and achieve electro-pop's holy grail on 'Another Breakfast With You', 'The Way That I Found You' and 'Play Girl'. Meanwhile, 'Paco!'s journey through department store voyeurism resembles a chilling upgrade of the British comedy 'Are You Being Served?'. After a while the squelchy keyboard effects and downturn in tune quality will start to grate a little and the need to include 16 tracks on this album seems a little excessive. As an exercise in turning ancient, primitive equipment into effective pop nuggets though, '604' can be hailed as a success.
