When LA musicians Russell and Ron Mael moved to Britain in 1973, they hit the pop world as Sparks and looked like oddballs, even in the context of the glam rock movement that made them welcome. Soon defined by their weird and wonderful 1974 single This Town Ain't Big Enough For The Both Of Us from the Kimono My House album, Sparks have now released 22 albums over four decades, each record inhabiting a bizarre world of its own.

Their songs were peppered with puns and pop culture nods, as well as nostalgia and jokey images, all mixed up in a kaleidoscope of musical references ranging from rock to opera to disco. They remain one of pop music's truly original and uncompromising acts.

The Sparks story is now celebrated in this unauthorised book, Daryl Easlea's exploration of their extraordinary drawing on hours of new interviews and research. Talent Is An Asset comes as close as possible to pinning down the quicksilver nature of two gifted musicians who have gone out of their way to remain unpredictable and elusive, forever entrenched behind a dazzling gallery of jokes, impersonations and musical eccentricities.
