John And Rudy Dopyera's collection of one-of-a-kind musical instruments is for sale at Elderly Instruments. If you know who they are, you've already clicked the external link, so I'll tell everybody else that the trademark "Dobro" is a contraction of DOpyera BROthers and their resonating instruments changed the sound of American music—blues, Hawaiian, bluegrass all rely on that haunting, sliding sound.
