Rayland Baxter’s smile shines on the Brighton Music Hall with his band on Saturday.

The band Chicago’s finally headed to the Rock ‘n’ Roll Hall of Fame, an honor that’s long overdue even if the group’s short on original members and hasn’t been vital in the rock ‘n’ roll sense for decades. Its early albums — especially the edgy 1969 debut Chicago Transit Authority — were landmarks, and Chicago still has its trademark original horn section and singer/keyboardist/guitarist Robert Lamm to help deliver the classics when the band stops at the Lynn Memorial Auditorium on Friday en route to April’s induction ceremony in New York.

Friday’s also a busy night at House of Blues with electronic jam-band Lotus’ trippy sounds, at the Sinclair with Seattle chamber-pop favorites Hey Marseilles, and at the Regattabar with broadly tasteful pianist Donal Fox and his “In the Pursuit of Beauty” trio with bassist John Lockwood and drummer Dafnis Prieto. Saturday brings the passionate, atmospheric songcraft of Nashville singer/songwriter Rayland Baxter and his band to the Brighton Music Hall behind his deftly dramatic Imaginary Man.
