I've been listening to JT since his debut album on Apple Records around 1970. With rare exceptions (i.e.: "Flag"), he has always put out great music both compositionally and performance-wise. "Hourglass" reaches new heights. His writing has clearly matured on this recording - more sophisticated and complex yet accessible compositions. The arrangements are understated but clear and beautifully crafted (listend to "Gaia"). His voice, always appealing, has also matured with a confident, rich presence. He continues to have a knack for choosing the best of the best side men. A must for any JT fan as well as any fan of excellent contemporary acoustic singer/songwriters.
