There are two bands with the name "The Rosettes".
The Rosettes are a wonderful two boy, two girl collaboration from Bradford UK. With a massively eclectic range of influences The Rosettes make music with CONTRASTS. One minute big 'Electro' beats and dirty guitars and the next, beuatiful harmonies and catchy synth lines.
Live they make use of a sampler, providing glitchy beats and sound effects galore, but this doesn't take away from the very 'live' feeling.
They are all very much firm believers in 'Style over Substance'.
