About 12 years ago (before CDs and MP3), a friend gave me a tape called "Last Band on the B Side", which is a collection of instrumental waltzes. I have no idea whether this was an actual published compilation or a home-grown one. But the waltzes are, for the most part, lovely. Here are the titles and artists (the ones I can read, anyway!). I know some of these folks now have 21st-century access to their music.
Keegan's Waltz and Jig -- Cathie Whitesides Cabri Waltz/Midnight on the Water -- Bill Spence Katrina Valsen/Brondums Hopsi -- Spelimenninir (?) Nerissa's/Larry's Waltz -- New England Chestnuts Waterfall Waltz -- Marshall Barron and Phil Merrill Margaret's Waltz (one of my favorites!) -- Trapezoid Joyous Waltz -- Jean Carignan My Home Waltz -- Strathspey Westphalia Waltz -- Arm & Hammer Stringband Kiss Me Waltz -- Bill Monroe
There are also two beautiful waltzes, "Gaelic Farmer" and "Rowan Davies", on Harbors of Home, the latest CD by Gordon Bok, Ed Trickett, and Ann Mayo Muir, which is available through Timberhead Music.
