ubu - heres the AMG link for you for the 'At Boomers' CD version on Japanese East Wind. There's a volume 2 of this also.
At Boomers Vol 1
There's also a set of Cedar Walton trio releases on Muse with this title, so easy to confuse..
Cedar Walton Boomers Vol 1
East Wind is a high quality Japanese label who released quite a bit of stuff by Farmer, Clifford Jordan, Cedar Walton and others during the 1970s, some of which was direct-to-disk ('The Pentagon' for example). Most of these were released domestically in the US by Inner City.
Farmer recommendations on East Wind include 'The Summer Knows', 'To Duke With Love' and 'Yesterdays Thoughts'. They are all superbly recorded and mastered, in typical Japanese style.
