Memorise this jazz catechism: and hey make a note of where you happen to be when you first hear Lovabye. A sacramental sextet on fire that cleaves to some key tenets in modernistic contemporary versions of hard bop and beyond. Yep, a pretty jaw dropping recording from the Boston tenor saxophonist Gregory Groover Jr recorded on the American player's 30th birthday last summer.

Two years on from Groover's Negro Spiritual Songbook, Vol. 2 (The Message), the very lush and at times romantic saxophonist whose sound connects with 1990s retro currents developed by the likes of Joshua Redman codified on Moodswing and revivified on the spirited message music of Long Gone. JD Allen, Melissa Aldana and Dayna Stephens are all in the vanguard of this New Melodicism as is Groover's fellow saxist Walter Smith III going back quite a bit and whose Return to Casual last year was tasty.

'Bygone Towers' here is spacious and the shape of it is open, giving room for Joel Ross' vibes and the drums of Marcus Gilmore to ruminate. Groover, like Smith, teaches at Berklee in Boston - the title track of Lovabye is the fifth of 11 tracks and is later reprised as a theme. Lovabye as noted previously on marlbank was produced by Smith and laid down in the studio last August. Blue Note vibes star Ross has pianist Aaron Parks who played Magy's Farm in Ireland fairly recently, the Glasperian bassist Vicente Archer whose Short Stories we liked last year and guitarist Matthew Stevens who recorded with Smith on In Common III and the ex-Vijay Iyer drum icon of his generation Gilmore (grandson of Roy Haynes) at the kit and excellent on Refract complete the band. Ross' solo on 'Byone Towers' is one highlight to pick out as too is a gorgeous motif that crops up on the restorative bliss of 'May All Your Storms Be Weathered' and so is the rumbling riffery Parks develops at the outset of 'Joy.' Soak this all in deeply - like yoga for body and soul.
