This is a great collection of rare and hard to find tunes compiled by Jeffrey Glenn. Hundreds of odds & ends by little known groups, famous singers, and famous singers before they became famous.
I have a collection of 135 titles (142 CDs) issued by Goldmine/Soul Supply record company. This is not a box set but rather it is a collection of albums that are similar in that they all are rare soul compilations by the same company. There are some tracks that are on more than one album but considering the scope and magnitude of this collection, the number of duplicated tracks is small. Some CDs have good artwork, some have none, most have some artwork of varying quality. All are 320 CBR MP3 and are fully tagged. Original post now has added CDs.
