| Character Information
John Coltrane was a jazz musician.
When Barchie created his band The Bartchies, he went to his sister, Librina, to get some tips about music. She told him to start by listening to John Coltrane, move to a little Dave Brubeck for fun and then finish with the master, Mr. Miles Davis. He told her he didn't want to get tips about jazz, to which she said she had no time to teach him about other genres as she must study.
