Editor's Note: First Notes is a weekly update of recent happenings in the world of music.
* Word was leaked over the weekend that a new Pink Floyd album, The Endless River, will be released this fall. The album, the band's first in 20 years, features new recordings dating as far back as 1994 and is considered the final work of the late keyboardist, Richard Wright. There are no plans for a tour, and Roger Waters is not on the album.
* A new study shows that music could be the key to good health and the solution to get people through pain. One clinical psychologist suggests that 25 minutes of music a day, 10 days in a row, can help alleviate back pain and provide for better sleep.
* A 50-year-old Motörhead fan in Germany suffered from bleeding on his brain after a bit too much headbanging. To relieve the pain, doctors drilled a hole ... in his skull ... to drain the blood. Take it easy out there, folks.
