It would appear that musical differences truly were at the heart of the break-up of the original Sugababes.

There is little common ground between these former band members' solo works.

Mutya Buena takes the most obvious path, styling herself as a British Kelly Rowland. She has a strong voice and appears to be well regarded in the industry.

There aren't many gals able to secure George Michael for a duet, as on This Is Not (Real Love), or hook up with the likes of Groove Armada on Song 4 Mutya (Out of Control). But sadly, Mutya's album is not terribly special.

Siobhan Dohaghy, however, really is a name to watch.

With her musical partner, James Sanger, whose previous credits include Keane, U2 and Brian Eno, Donaghy has delivered a left-field unfinished mini-masterpiece.

Ghosts is a hotchpotch of psychedelic images, motifs and styles. The music is exciting, if too embryonic and experimental. But at least this work is original and fresh.

Unfortunately, somewhere along the line, the all important killer pop song got lost in the mix. Ghosts is reminiscent of The Eurhythmics' In The Garden, whereby the energy and ideas are present, but lacks commercial focus.

Ghosts is too random and haphazard to attract a mainstream audience, but given time Donaghy and Sanger could become a major musical force.
