Tim Bluhm has announced via his Facebook page that he and wife/musical collaborator Nicki Bluhm will part ways in both their marriage and their professional work together.

Tim notes in his message that he and Nicki “remain friends and truly want the best for each other.”

The two joined forces starting in 2007 when Nicki sang for Tim’s band The Mother Hips, resulting in Tim offering to mentor Nicki and quickly forming The Gramblers to back her up. They released a collaborative solo album, Duets, in 2011.

Here’s the full note from Tim Bluhm, echoed on Nicki Bluhm and the Gramblers’ Facebook page:

After much deliberation Nicki and I have mutually decided to part ways both in our marriage and professionally. We remain friends and truly want the best for each other. We ask that you respect our privacy during this challenging time in our lives. Thank you.
