So there was a little snag in terms of the Giulini in Chicago (DG), but Amazon replaced a copy that was lost in the mail. Both are quite nice, but in terms of the performances I am far more interested in the recordings with Chicago (than LA). The repertoire is a bit more adventurous at least relatively so. In the Chicago box, you have Dvorak Symponies 8 and 9, Schubert Symphonies 4, 8, and 9, Prokofiev #1 and Mahler #9. In the LA box, you have Beethoven #3, 5 and 6, Brahms Symphonies 1 and 2, Schumann #3 and Tchaikovsky #6. All pretty much mainstream canon, but the Chicago contents still grab me a bit more.
The Chicago set can be now bought from amazon.co.uk for £8: http://www.amazon.co.uk/gp/product/B004TNZVEY/ref=ox_sc_act_title_1?ie=UTF8&m=A3P5ROKL5A1OLE !
