Meanwhile, Spin CDs is saying the album has been remastered again...
ELO’s eponymous debut album has been painstakingly remastered for its 40th Anniversary and expanded with over two hours of bonus material. Now spanning a CD/DVD double, the album includes the original Quad mix in DTS 96kHz/24 bit 4.1 surround sound, the original stereo master in high-resolution 96kHz/24 bit PCM, the original ‘10538 Overture’ promo film and extensive liner notes charting the history of the release.
If there's a substantial improvement over the 2001 edition, I will be surprised... unless they are just referring to the DVD...
