Dissolving barriers of time, cultures and geography, the Selkirk Trio offered a choice 90 minutes to an appreciative all-ages assemblage Sunday afternoon at Castlegar United Church.The event, another memorable installment in the Kootenay Gallery's TD Bank Sunday concert series presented a beautifully varied couple of sets, spanning the musical spectrum from Beethoven to more modern works from Cuban and Croatian composers... as well as a featured pieces by "Godfather" composer Nino Rota.The trio closed with Cole Porter's "Night and Day."The group was in fine form, having just about made it to the end of a stint of more than 15 performances in seven day.
