George McPhee has been Paisley Abbey’s organist and Director of Music for 60 years, and for quite a few of them has been providing music for Science Festival concerts on Sunday evenings.

To mark the occasion, he plays works from some of the great organ composers – Sweelinck and Samuel Scheidt, Scheidemann and Reincken, Buxtehude and Bach. He is joined by the Mayfield Singers for several of the works, including two of his own – A Celtic Prayer, and the title piece from a poem of John Milton.

Flautist Ewan Robertson narrates.

After the concert, George McPhee will be in conversation with Ewan Robertson at the Orkney Club to reflect on what makes the pipe organ capable of producing such glorious music. The Most Magnificent of All Instruments starts at 9.30 pm.
