John Brennan is a singer, guitarist, and songwriter from the Philadelphia area. He performs at various music venues, festivals, bars, restaurants, breweries, and coffee houses. 


He performs solo as well as fronting his blues band/duo John Brennan Blues. His solo style has a Blues based sound mixed with Roots Music, Southern Rock, 60's and 70's Classic Rock, and Rockabilly. 

John Brennan Blues performs as a band and a duo with keyboardist Adam Darer.

When performing as a full band they collaborate with some of the finest blues musicians from the Philly blues scene. They incorporate a variety of blues styles including acoustic delta blues, electric Chicago blues, West Coast blues, and Rockabilly. Whether performing as a full electric band or a smaller acoustic duo, they keep the Blues true to it's roots.

In September 2016, he released his debut self titled E.P. featuring four original songs.

​The songs "Nothin' to Lose" and "Stranger" are the most blues influenced with a hard hitting rock edge that features his raw, fuzzy guitar tone that produces catchy slide riffs and tasteful leads. "Keep Rollin'" and "Going Away" reflect a more "traditional" Rock music style incorporating elements of "Southern Rock" and "Rockabilly" while maintaining a blues feel to the songs.

All four songs are sung by John Brennan and all additional instruments were performed and recorded by him.

In July 2021, he released two new singles: his solo single "Lonesome Road" and The John Brennan Blues single "Nothin' To Lose". 

He is currently working on a new solo E.P.  which features new songs plus re recordings of "Going Away" and "Stranger". 

A John Brennan Blues album is also in the works.
