Why did Blue Note switch from the 1500 to 4000 series?

[Dmitry]

The last 1500 series Lp was BLP 1599, Bennie Green - Soul Stirrin' (recorded on 4/28/58). Imo, the logical continuation would be to go on to 1600, etc. Instead they started the 4000 series. The first Lp in that series was BLP 4001, Sonny Rollins - Newk's Time (recorded on 9/22/57). Would it be correct to assume that for a time the two series were being released side by side?

Wasn't there a 3 Sounds LP, #1600?

I think 4000 release begins in around 8/9 58. I don't think 1500 and 4000 were released side by side : most recording date of the 4000 are from 11,12 / 58, 1/59 etc... (there's a BLP 1600 : the 3 sounds)

I think 4000 release begins in around 8/9 58.

Actually, BLP 4002, Jimmy Smith - House Party was recorded on 2/25/57 & 8/25/57.

In comparison, BLP 1593, Lou Donaldson - Blues Walk was recorded on 7/28/58.

But all of this is somewhat secondary to me; I'd rather know why Lion and Wolff started the 4000 series when they could've just made a transition from the 1500 series onto 1600 and on. Aren't you curious also?

A kabbalah specialist might have the answer

[Stereojack]

There were a number of singles (78 & 45) issued in 1500-1600 series. Perhaps Blue Note found that this duplication between LP's and singles was causing confusion at the distribution level, and so they began the 4000 series.

Yeah...Madonna would know...
