Hints of Fleetwood Mac/Stevie Nicks, great use of vocal colours - you have
some good songs, but could really do with better production - the vocals are
great, but the tracks on myspace suffer from production not living up to the
songs potential. Notabley the drum sounds aren't great, the songs deserve
meatier, slicker (US). Imagewise, a little less casual in couple of setups
wouldn't go a miss - some good head shots perhaps?

Get a youtube player and a retail element on you site (the player on
http://www.greymatter-music.co.uk/video.php only gave me a squashed and very
blured view of the live performance). I realise that you have you own
Greymatter site, but it doesn't hurt to double up.
