The early Journey instrumental music was always good soundtrack material to use in media. I remember when I was in radio class in college using this track as background music for a football highlight show. I tell you--PERFECT football highlight music, this one!
Journey of the this era induces a mind-blowing trance. Later Journey, well, you can sing along to it while you drive. Similar shift happened with Chicago, unfortunately.
They should have changed their name to "The Steve Perry Pop Band" when he joined. It was no longer Journey once he joined. Sep 27, 1975 Journey opened up for UFO and Montrose at Winterland. One of the best concerts I ever saw.
