Glad some one took this one.
I love those old mixes not for the audiophile quality but for the fun of it. (damn it the yankees just hit a two run homer)I'm distracted easily...
back on topic, I like turning the old balance knob to the far right or far left on those old albums. Some fun surprises there. I'm also easily entertained.

Ever hear Hymm to an Older Generation from Airplane's After Bathing at Baxters spun to the extreme on the balance knob? Grace and Jack isolated! Neat stuff!
My original question was what are other examples of such that are equally entertaining in isolating good bits?
