Phantasm, a 6-year old quartet basked in London and widely admired for its recorded work, made its West Coast debut with a revelatory and affecting survey of the golden age in 17th England. Although for the most part linear rigor was the driving force here, there was never anything mechanical about Phantasm's playing. Rich in subtly shaded colour, it moved with an organic ebb and flow, clearly thought, deeply felt and communicative on all levels. ... Phantasm also brought along a fine singer. Geraldine McGreevy's soprano is a suave, flexible instrument in its own right: pure, gleaming and wielded with relish.
