Want to hear the first song on Dosh's new album? Yes, you do, even if you don't know it. Click here for a free copy of the track "Subtractions," newly available to hype the local instrumental wiz's fifth album, "Tommy," due out April 13 on the Anticon label.

The disc is named after Martin Dosh's close friend, sound engineer Tom Cesario, who passed away last January. Martin says he basically turned to playing music in the weeks afterward as a way of maintaining, and he wound up with a whole record's worth of material before spending the rest of 2009 on tour with Andrew Bird (for whom Dosh plays drums/keyboards). "Subtractions" kicks off the new 10-song collection and suggests it's not a downer kind of album, despite the context. Saxophonist Mike Lewis and bassist Chris Morrissey play on this track. Other guests on the album include Bird, Jeremy Ylvisaker and Ryan Francesconi.

Dosh kicks off a month-long tour with Eyedea & Abilities at Pizza Luce in Duluth on Thursday (Jan. 28). He has a few Minneapolis gigs booked around the CD's release date, including the Bedlam Theater on April 11.
