Vertical Squirrels is a Canadian quartet — Daniel Fischlin, Ajay Heble, Lewis Melville and Ted Warren — that loves to work with other musicians, as confirmed on their latest album, Time of the Sign. The album includes organic sounds, hurdy-gurdy, guitar, flute, percussion, and wind instruments all merged in a very interesting way of improvising that comprises minimalism, post-rock, free jazz, and spiritual jazz. This is not reminiscent [as per their first album with AM] of the work of Frank Zappa, foreign, or German rock bands from the 70s — and I think fans of The Necks will love the album Time of the Sign.
