I am that rarest of beasts -- a George fanatic from Canada. I first heard of them on a Qantas flight to Sydney, and was immediately a fan for life after hearing "special ones" (like many others, I suppose). I bought both "Polyserena" and "Unity" as soon as I had the chance while in Australia.
Of course, "Polyserena" is a very special album. Most of the songs (esp. Katie's) are very catchy and beautiful. George is one of those rare bands which seems capable of just about anything musically, and they pull out all the stops on Polyserena (including doing their own horn arrangements, which, on the penultimate cut, seem to pay homage to Gil Evans, a pretty amazing feat for a bunch of 20-something popstars from Oz!). They seem to be just as much a jazz ensemble as a pop group.
I must say that it took me a lot longer to get into "Unity". The songs were not as catchy as those on Polyserena, and there didn't seem to be any real standout track like "special ones". However, now, after a month or so, I find that I am listening to Unity more than Polyserena. Unity is a work of real maturity, and the music is deeper than Polyserena. Here they have added an orchestra, and hired Aussie jazz musician Paul Grabowsky to write their horn and orchestra arrangements (Katie and Paul did a duet album together which I have yet to hear -- next trip to Oz).
The most pleasant thing about Unity is that Tyrone's songs are a vast improvement over those on Polyserena. It took him a bit longer to find his compositional mojo than his sister Katie, but found it he did on Unity. I find that I actually prefer his songs on Unity, especially "Fortunate Smile" and "Change", which seem to form a bit of a suite, along with Katie's "Jaded". He has a wonderful piano style which provides just the right backbone for his tunes. My other favorite tracks are "Still Real", "Today", and "Surrender". That last one took me a while to appreciate, but now it's probably my favorite on the album!
If you, like me, bought this album and were disappointed with it, please listen to it for a few days. It will definitely grow on you!
