“Ladies and gentlemen” begins the announcer, a parodic BBC-style throwback to a politer, simpler age. Not that he promises simplicity exactly, and certainly not musical purity, from the album “you now have in your hands by the group Never”. The ‘concert programme’ you're about to hear, he explains, is a mix ranging from 1940s swing, bebop, “experimental groups of the sixties and seventies, modern jazz and electricity”. And he's not kidding about the stylistic variety either, though what's most impressive is the voracity with which Zhenya Strigalev's trio-plus-guests eat the fare up, barely pausing for breath across this 73-minute, 20-track set recorded in Berlin last year. The first musical track proper, ‘Bio Active’, begins with a precision-tooled menacing throb from the rhythm section of drummer Eric Harland and bass guitarist Tim Lefebvre, who performed on David Bowie's swansong, Blackstar. Strigalev echoes his hero Sonny Rollins on the teasingly titled calypso-undone of ‘Some Thomas’. The cameos from the guest players add texture, and the spirit of Frank Zappa might be glimpsed by some among the grooves (‘Are You Manageable?’ is a great Zappa-esque title). Sometimes it's slow and scratchy (‘The Slow Rub’), sometimes it's fast and skittering (‘Not Upset [Coda 7]’); always it's a surreal, impressive brew.
