It wasn't until a full ten minutes after Carrie Thomas finished her performance that Harrison Clark snapped out of his trance.
His strong reaction was due to two main factors.
First was the quality of "Self-Combustion" itself, which was so excellent that he could not remain calm.
With Harrison's current ability to appreciate music, he believed that "Self-Combustion" was not inferior to "The Fire".
He believed that others would also share this opinion; it was a classic that could withstand the test of time and be passed down for thousands of years.
This was both within reason and beyond his expectation.
In his eyes, Carrie Thomas seemed like an inexhaustible gold mine.
Even if he exhausted it with a single stroke, the gold in the mine would still re-emerge like the bubbling spring water by the riverbank.
Second, he understood the story depicted in the song.
Just the guitar accompaniment in the introduction was enough to immerse Harrison in the artistic conception of the song.
