Sol Weber's rounds collection,
Galore, and his Unofficial Set of Additional Rounds
and the best collections you can buy.
Rounds Galore has over 340 rounds, new and old, in a convenient spiral binding,
beautifully laid out. With chatty background information about the rounds,
and their composers, and folksy commentary throughout.
The Unofficial Set has 150 more rounds, in a much less expansive layout:
just the rounds, often several per page.
