Sam has documented two albums with HIS project, “Wistful Thinking,” a chamber-jazz ensemble with Brandon Coleman (guitar), Matt Wiles (bass), and Chris Coles (alto saxophone/pedals). The first album, The Long Middle, was released on July 30th, 2021 on Outside In Music. THE SECOND OUTSIDE IN MUSIC RELEASE, BUSY BODY, WILL BE RELEASED OCTOBER 28th, 2022.

The Long Middle music pulls influence from the small bands of Bob Brookmeyer, Kenny Wheeler, and Paul Bley, but tinged with folk and electronica. The second album, Busy Body, contains a radically different sonic landscape and features percussion master Jamey Haddad, Grammy-nominated drummer/composer Dan Pugach, and woodwind/composer phenom Brian Krock.

In addition to his latest endeavor Wistful Thinking, Sam is also active as a big band composer, and since September 2019, he has been a member of the BMI Jazz Composers Workshop in NYC under the direction of Andy Farber and Alan Ferber. Most recently, Sam was commissioned by the International Association of Jazz Arrangers and Composers, and the resulting piece Another Day In Which To Excel will be released as a single in January 2021. The piece is dedicated to his grandfather, Dr. Jim Blakeslee who stated “Another Day In Which To Excel!” every morning upon waking up, even after his terrible diagnosis of ALS and has served as a mantra for him during the struggling times of the recent pandemic. All of the proceeds from the release will be donated to the ALS Foundation in honor of him. The single features some of NYC’s most compelling artists including Remy Le Boeuf (alto/tenor saxophone/flute clarinet, Andrew Gutauskas (bass clarinet/baritone saxophone) Stuart Mack (trumpets) Jennifer Wharton (bass trombone), Brandon Coleman (guitar), Manuel Valera (piano), Edward Perez (bass), and Jimmy Macbride (drums). 

Sam also leads the "Sam Blakeslee Large Group" which is a 17-piece contemporary jazz orchestra that features original compositions and arrangements in a variety of styles and moods.The Large Group held a monthly residency at Blu Jazz in Akron, OH from January 2016-July 2017. Blu Jazz was recently voted one of the "Worlds Best Jazz Clubs" by Downbeat Magazine. Through the Blu Jazz Masterclass Foundation, the group featured many special guest artists including from Akron-guitar virtuoso Dan Wilson (and member of the Joey DeFrancesco's Trio and Christian McBride's Tip City), Grammy-Nominated NYC jazz artists Dan Pugach & Nicole Zuraitis, Dave Smith, as well as renowned pianist and composer Bill Dobbins. One of the artistic missions of the Large Group is to constantly expand the repertoire of the music across many styles, leaving both the audience and band members guessing what each concert will hold. A live compilation of the residency at Blu Jazz was released exclusively on Bandcamp in October 2018, and will be re-released on all streaming platforms by Cincinnati-based record label Golden Mean Records on March 19th, 2022. The album features the talents of Northeast Ohio jazz artists and longtime musical compatriots Dan Wilson, Chris Coles, Dave Morgan, Bobby Selvaggio, and Theron Brown. 

The Sam Blakeslee Quintet features some of NYC's dynamic musicians including Jorn Swart (piano), Cory Todd (bass), Dan Pugach (drums), as well as Cincinnati-based guitarist Brandon Coleman. In its short existence since February 2016, the group has done several tours of the Midwest and East Coast. In September 2016, the quintet recorded at Systems Two Studios in Brooklyn to record Sam's debut album "Selective Coverage" which was released in October of 2017. The album received glowing critical acclaim from several jazz publications, including a 4-star rating from All About Jazz.
