Revealing the news on Instagram, the Grandaddy frontman revealed, "Best "merch" idea ive ever had. I recorded an exclusive 11 minute long instrumental dedicated to my late dog tippy."

The new offering is extremely exclusive, as it's only available to those who donate and buy a photo/card from San Francisco's Swedish American Hall venue.

Grandaddy's last album was 2017's Last Place. Last year they released a standalone single, "Bison on the Plains".

The download codes are on sale now at San Francisco's Swedish American Hall, with all proceeds going to Muttville Senior Dog Rescue.
