When you see this list of albums I've posted here, you might think I'm trying to tell you that you should like classical music, and that's not my intention. You like what you like -- especially on a road trip. Most people put on music that will entertain them and keep them from getting bored. I'm just trying to suggest another type of music for your car: the Road Trip Soundtrack. How about music that goes with the landscape? And in Arizona, that landscape can be very strange.
One of the best soundtrack moments we had was unexpected -- it happened on I-40, just outside Holbrook, as we approached the big power plant on the South side of the Highway. The outside temperature was under 40 degrees F, so the steam hung over the power station in a massive formation, instead of evaporating. I had put on Mahavishnu's album, Apocalypse, and it couldn't have expressed the weirdness of that sight better if it had been written for it.
If you've got a car with a good sound system, you may want to try these. Or even at home. As for me? I had to return Jay Silverwheels. I have to drive my Crudmobile for one more year.
