How about a vinyl record of John Coltrane's "A Love Supreme" album or if your friend doesn't have a record player, you could also give them a copy of the album in CD or digital format. Another option could be a book about John Coltrane, such as "Coltrane: The Story of a Sound" by Ben Ratliff, which explores the musician's life and artistry. You could also consider concert tickets to see a jazz show or festival featuring other artists that your friend enjoys. Alternatively, you could give them a personalized gift such as a piece of art inspired by John Coltrane, or a personalized playlist of his music curated just for them.
