Just to note, due to the law on copyright in the UK and EU, many UK based companies any music that has been released over 50 years is in the public domain. Thus, EU based companies churn out cheap as chips cds, without paying any royalties to artists or license holders. Sometimes the music is taken straight from vinyl, other times from cd releases. Hence why this cd conveniently ends in 1961.
The fact is, Hip-O Select and Motown UK have already done a great job in re-releasing and remastering Motown tracks. Buy this if you want a taster, but please be aware that no one who has any thing to do with Motown has had anything to do with the set. These will not be the best quality versions, and the people who contributed to this music won't see a penny of the profits.
As for music, its a bit misleading to call this the sound of Motown. As someone who has all of the Complete Motown single box sets, and pretty much every UK and US cd release over the past 15 years, I wouldn't call much of the music from 1959-1961 as being representative of the Motown sound. Smokey and the Marvelettes always stood out from this period, with some of the stronger tracks. But artists like Marvin, The Temptations and the Supremes are still in the early stages of their careers. So this is a nice taster for early Motown, but you won't see most of the more recognisable Motown tracks here. Ones that the average person would probably have already heard are Please Mr Postman, Money and Who's Loving You (as covered by the Jackson 5).
Seriously, if I was a potential buyer I would avoid this and instead spend the money instead on any Hip-O select release. Listen to, it, discover some great music and really fall in love with the depth and untouchable brilliance of the Motown vaults. Then see how in a year or two that cd is worth over a £100, and pat yourself on the back for buying a great official cd that was also an investment as a real piece of Motown memorabilia.
