Love Decca pressings and I don't even listen to Classical!
Rolling Stones, Them, Zombies, The Artwoods, Leafhound, Bread, Love & Dreams, The End, Human Beast, The Applejacks, Small Faces, Black Cat Bones... to name a few, have all had outings on Decca and yes they sound superb; not a bad pressing among them unlike pressings found on many other labels. So if you're a peppermint twister who thinks they're missing out, theres something to be getting on with..
I also believe Parlaphone contracted some of their pressings out to Decca, including copies of The Beatles White Album, Sgt Peppers, Please Please Me..
