Excellent pair of recent (i.e. up to date production values/technical quality) HD Prog-rock concerts, best in class examples of Prog rock.
Steve Hackett - Genesis Revisited - Live at the Royal Albert Hall
For Prog noobs, try Dancing with the Moonlit Night 7:15-15:00. Great example of early 70's prog/art-rock and the classic Genesis sound & style, with typical changes in mood and time signatures throughout the song, with excellent "ethereal" beginning and ending/outtro and a rocking mid section. The song takes you on a journey as any good prog-rock should
...and of course, an outstanding performance of Supper's Ready, regarded by many as the Greatest Prog-Rock song of all time, 1:38-2:05.
Like any good prog/art rock, no judgements until you have auditioned a minimum of 5 times- occasionally takes that many listens to "get it".
Prog rock isn't about a beat that hooks you, it's about stylistic complexity and an experience over time, not the moment.
Both of these concerts are true gems, with veritable prog/art rock royalty performing guest vocals and/or instruments.
