"Presto is a remarkable producer..."- okayplayer.com -------- Organic, soulful and refreshingly contemporary, Presto has spent the last decade perfecting a production style that infuses hard-hitting hip hop beats with an ethereal touch of jazz.

As the pioneer behind the critically-acclaimed independent label Concrete Grooves, Presto has put forth several selections reflecting his eclectic range of influences, including DJ Presto "Breakin Concrete", V/A "Impressions on Concrete", LOWD "Calligraphy", Presto "Jazz Juice", Presto "Inflight Instrumentals", V/A "Next Impressions", Kim Hill "Right Now", Presto "Magic LP", and Presto "State of the Art". This extensive discography is especially impressive when one considers the quality of each release. Never one to be swayed by trends, Presto has always been able to focus his energy on creating quality music--songs that will withstand the test of time and eventually find their place among the crates of future DJs. Such versatility is evidenced in the score of artists he has worked with, including such luminaries as Sadat X, Large Professor, CL Smooth, T Weaponz, Fatlip, O.C., Sach, Kim Hill, Blu, LOWD, Mr. J Medeiros (the Procussions), Raashan Ahmad (Crown City Rockers), DJ Smash, and Nobody as well as his work on Mark Farina's Mushroom Jazz series and his musicianship in the Wayward Saints.
