Well, that’s a pretty big one.
The man cultivated a real thunderous bass sound, whether with Cream or any of his other heavy blues projects. Every group he was in was a “supergroup” before the term even existed in rock music.
Then he nurtured his psychedelic side throughout his solo albums, often adopting a folksy feel, keeping it tender.
Whether or not you like everything he did (I don’t, to be honest) you can’t deny Jack was a huge presence in a crazy and amazing time in rock history.
Much respect. Rest easy, Jack.
