Steve Cropper, the legendary Booker T. & the MG’s guitarist and beloved member of The Blues Brothers band, has died at the age of 84. The news was confirmed by the Soulsville Foundation, marking the end of an extraordinary era for one of the most influential musicians in American soul and rock history.

Pat Mitchell Worley, president and CEO of the Soulsville Foundation, shared that Cropper’s family informed her of his passing on Wednesday in Nashville, according to the Associated Press. Soulsville operates the Stax Museum of American Soul Music—built on the grounds of the original Stax Records studio—where Cropper spent many of his most formative years and helped craft the unmistakable Memphis soul sound.

As of now, no official cause of death has been released, though longtime associate Eddie Gore shared that the guitarist had recently suffered a fall and was at a rehabilitation clinic the day before his passing. Gore added that Cropper had been working on new music and described him as “such a good human,” saying those who knew him were “blessed to have him.”
