On September 7, Toubab Krewe will release its second studio album, TK2. As we’ve reported, the disc quite fittingly will be released on Nat Geo Music. A few weeks ago, Relix.com posted a video that offered a look at the sessions. Now the group has now shared an initial tune from the recording. The song “Holy Grail” has now been released to Relix.com, where it is now streaming. Toubab Krewe will celebrate the release of TK2 with a special show at Brooklyn Bowl on September 10.
