"For Greg Spero, the cross-fertilization of jazz with pop, heard so clearly on Spirit Fingers, carries on through 12 Spero compositions ripe with melody, beat and an uncanny spirited attitude."
- John Ephland // Down Beat Magazine
"If you’re in a mood for music that recalls the high fusion era of albums like Stanley Clarke’s Journey To Love or
Di Meola’s Elegant Gypsy, this will definitely do it for you.
- Phil Freedman // Stereogum
"...'inside,' a rolling,  cinematic composition whose main attraction is the polyrhythmic groove..morphs and changes like a weather system."
- Nate Chinen // WBGO, NPR
"...'being' is a chameleonic groove anchored by impeccable arpeggios that rise and fall against a dense, driving rhythm. SPIRIT FINGERS is a well-oiled machine...effortlessly balancing whimsical notions and melancholic chords with fiery percussive statements that capture the complex and bittersweet moments of life."
- Karas Lamb // Revive-Music
"Spero’s ambition is powerfully manifested in his new band SPIRIT FINGERS (formerly known as Polyrhythmic), a dynamic ensemble of uber-talented young musicians whose energy, passion and innovative approach stake out exciting new territory for exploratory music on their eponymous debut..."
- Jon D'Auria  //  Bass Player Magazine
"...Spero's adventure has reached escape velocity...this is a seriously good album."'
- Brian Morton // The Wire
"Greg Spero, an undeniably gifted pianist... assembled for his project amount to a veritable supergroup in terms of their prodigious talent...Imbued with preternatural levels of skill and a high replay value, this is one album where the much hackneyed term "fusion" seems an absolutely appropriate term."
- Roger Farbey // AllAboutJazz
“…Pianist Greg Spero has a way with plaintive loopingpatters..and is adeot at building solos of great melodic richness. The group really dazzles when piani, bass and guitar combine for some truly jaw-dropping unision lines.”
- Mike Flynn // Jazzwise Magazine
