Regarded as one of the pioneering and most well-respected Industrial drummers, Rieflin was also a master multi-instrumentalist who played piano, guitar and bass. R.E.M. would break up in 2011. He worked with the group from 2003 through its disbanding in 2011, as well as the Minus 5, a band (occasionally featuring Buck) that was formed by fellow R.E.M. auxiliary member Scott McCaughney, as well as a project called Slow Music with Buck and Crimson founder Robert Fripp, and a project called the Humans with Fripp and Fripp's wife, singer Toyah Wilcox. He further explained that "they are all lovely guys - very smart, funny, and significantly, among the most generous and big-hearted people I have ever met". In 2013, he joined King Crimson and was one of three drummers, and after a hiatus in 2015, he continued to contribute to the band until he took an indefinite hiatus from the group in 2019. Riefin would start appearing on tours and performing with the band from 2015 up until 2018.More news: Morris County Jail Inmates To Be Released
