PETERBOROUGH — Aztec Two-Step will perform Saturday, Feb. 2, from 7:30 to 10:30 p.m. at Bass Hall, Monadnock Center for History and Culture, 19 Grove St.

Renowned folk-rock group Aztec Two-Step now features lead singer, songwriter and original founding member Rex Fowler, along with multi-instrumentalist Dodie Pettit, bassist Steven “Muddy” Roues and drummer/percussionist Roger Post.

Fowler’s new ensemble will perform vintage and recent Aztec Two-Step fan favorites as well as forgotten gems.

Originating from a chance meeting at a Boston folk club open mic night in 1971, Aztec Two-Step burst on the scene in 1972 with its self-titled debut album on Elektra Records. Its first album and three subsequent albums for RCA Records made the duo staples of progressive FM and college radio, helping to usher in the folk/rock music of the 1960s into the 1970s and beyond.

Fowler, along with his partner, Neal Shulman, spent a lifetime making music together. However, after 47 years of recording and nonstop touring, Shulman has retired.

In this new era, Fowler continues to expand the legacy of Aztec Two-Step’s music as he introduces new band members Pettit, Roues and Post.

Tickets are $25 in advance, $30 the day of the show. For more information, call 924-3235 or visit monadnockcenter.org.
