Fischer next lived in Detroit, Michigan, whereupon, after first hearing the vocal quartet The Hi-Lo's in a live performance, he promptly offered his services. Over the next five years, Fischer recorded several albums with the group, serving as pianist and, on occasion, arranger. In addition, he contributed several vocal arrangements, making his debut in that capacity; it was these arrangements that Herbie Hancock would later point to as a major influence: when I really learned some much farther-out voicings - like the harmonies I used on "Speak Like a Child" - just being able to do that. I really got that from Clare Fischer's arrangements for the Hi-Lo's. Clare Fischer was a major influence on my harmonic concept... I heard some of his last records, and he was still doing amazing harmonic stuff. And, of course, he was a wonderful pianist, too. But it was those vocal harmonies that were the first thing I heard. I was in awe of him.
