Power (b1977) is perhaps the outstanding British instrumentalist of his generation, and not only a viola player but, as this disc richly demonstrates, a violinist, too. Hans Keller long ago observed that the distinction is, anyway, fatuous. Power’s viola sound has a notable seductiveness, a sort of electric sweetness, but his genius for phrasing is as effective in Benjamin’s 1924 Violin Sonatina (more substantial than the title suggests) as in his searching 1942 Viola Sonata, the focus here. A virtuosic arrangement by the sonata’s dedicatee, William Primrose, of Benjamin’s 'hit', Jamaican Rumba, ends the sequence.
