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.
An epic 100 CD chronological documentation of the history of jazz music from 1898 to 1959, housed in four boxed sets. Each box contains 25 slipcase CDs, a booklet (up to 186 pages) and an index. The booklets contain extensive notes (Eng/Fr) with recording dates and line-ups. 31 hours of music in each box, totalling 1677 tracks Each track has been restored and mastered from original sources.
