Nostalgia Concert Series features the harmony-driven duo of Bill Bowen and Joan Friedenberg performing as the PinkSlip Duo, The Duo distinguishes itself by unique arrangements and never using recorded tracks. PinkSlip can make use of guitars, keyboard, harmonica, banjo, drum machine and various percussion instruments to create a rich full-band sound when needed for dancing. They devote hours devising clever and complex arrangements to make their two voices sound like more.   But when covering Simon and Garfunkel, they maintain the simple, mellow sound of two folk singers and a guitar.

PinkSlip’s repertoire contains Beatles, Peter Paul & Mary, Simon & Garfunkel, Dylan, Everly Brothers, Crosby Stills Nash and other 60’s  (late 50’s – early 70’s) close-harmony artists, in addition to having a limited selection of songs from the 80’s- 2010’s, songs in Spanish, and Jewish songs.
