Very Urgent is a fine first "official" foray into the Eurojazz (and wider) consciousness but it's not the Brotherhood of Breath. It's a lot starker (rugged small-group distilling its influences). It's freer than the ZA recordings of the Blue Notes, Gwigwi Mrwebi, et al, but not as unfettered as the 1970s edition of the Blue Notes that recorded for Ogun.
Up To Earth is an excellent, ragged affair that has more in line with later/BoB work. I recommend both.
