Youtube videos explaining suffix tries, trees and arrays, as well as BWT and FM-index

Regarding the INF4350 lecture today about suffix tries, trees and arrays, as well as BWT and FM-index, I would recommend watching three good Youtube videos where Ben Langmead explains these data structures very well. Langmead is the main author of Bowtie, one of the most popular tools for mapping reads to a genome.
