It’s a big week for classic rock fans: The Who’s iconic release Who’s Next just celebrated its 50th anniversary, while Metallica’s pivotal Black Album just turned 30. Those two mighty musical milestones are more than interesting enough to be the subject of today’s episode of Sonic Reducers. Join the one and only Eric Alper and I as we discuss the two albums, pick our personal favourites (sorry, Metallica) and ponder whether any contemporary artists and LPs will be remembered decades from now. Sonic Reducers: One topic. Two music geeks. Five minutes. Everything you need to know.
