Wow, this pair were really good. Great skills. Great composure in the face of heavy George Street aural competition. And great material to showcase their combined playing talents. Sounded like Nyman or Glass - maybe a contemporary version? Anyway, they were so polished it made me wonder whether it was one of those cases your hear of where members of the SSO or similar will 'slum it' on the streets just to see reaction. Went to an unusual 2 minutes on this act.
