Why does Kaira ride in the band's bus and whose music does the band play for her?

Kaira DeLeon's show travels through Texas. Kaira, desperate for company, leaves her own lavishly equipped bus to hang out with the band in theirs. Their comments about Bob Dylan and Janis Joplin meet with confusion from Kaira, but when they start playing Joplin over the sound system, she immediately connects with the singer's raw, bluesy emotion.
