A lecture for those who grew up on heavy guitar riffs and those who are just discovering the world of heavy music. Guests will listen to early recordings of the cult band on vinyl, analyze the hidden meanings of the lyrics, and learn how the famous dark sound was born, forever changing the perception of rock. This lecture will feature a lot of music. Guests will be invited to listen closely to the details of Black Sabbath tracks: heavy riffs, slow tempo, dark harmonies, and that very sound that laid the foundation for an entire heavy scene. Listeners will discover the techniques that created the feeling of dark, viscous sound and why it feels fresh despite the decades that have passed. There will also be an excursion into the history of the band. The lecturer will recall the history of the creation of key albums, important events in the musicians' lives, and their personal crises. The influence of the band on other genres will also be discussed. From heavy blues, metal will gradually grow, and then branch out into subgenres-from contemplative slow compositions to more actively sounding directions. A separate topic of the evening will be the personal experiences of the listeners. The host will invite guests to share what images arise for them during listening, which phrases they particularly remember, and why stories of darkness and disappointment support rather than pull down.
