On February 14, 2023, the group, still led by Steve Katz and Roy Blumenfeld, released a new collection of tunes, called "Evolution".

The Beatles' arrival in the United States earlier in the year muted the folk and acoustic blues movement that had swept the US in the early 1960s.

Later in 1965, the group added singer Tommy Flanders and changed its name to The Blues Project, as an allusion to Kalb's first foray on record.

[3] Kooper, who had worked with Blumenfeld and Kulberg during sessions for his contribution to the What's Shakin' compilation,[4] was invited to join the group.

The band began recording their first album live at Greenwich Village's Cafe Au Go Go in late November 1965.

[3] Projections contained an eclectic set of songs that ran the gamut from blues, R&B, jazz, psychedelia, and folk-rock.

[5] A fourth album, 1968's Planned Obsolescence, featured only Blumenfeld and Kulberg from the original lineup, but was released under the Blues Project name at Verve's insistence.

[3] These albums did little to excite the public and since then, the group's activity has been confined to a few sporadic reunion concerts, such as when the Blues Project played a fundraising concert at Valley Stream Central High School in New York, promoted by Bruce Blakeman with the proceeds going to the Youth Council and the US Olympic Committee.

In 1969, flutist/bassist Andy Kulberg and drummer Roy Blumenfeld of Blues Project formed the band Seatrain with Jim Roberts, ex-Mystery Trend guitarist John Gregory, former Jim Kweskin Jug Band violinist/fiddler Richard Greene, and saxophonist Don Kretmar.
