long story short, he didn't enjoy playing loud music, and the only thing he did that was remotely even proto punk was the 1st modern lovers album, which was not released until years after they broke up.
Since the mid-1970s, Richman has worked either solo or with low-key acoustic and electric backing.
In 1972, they recorded a series of demos with producer John Cale (formerly of the Velvet Underground). Among these songs were the seminal "Roadrunner" and "Pablo Picasso" which were eventually released on the group's post-breakup album, The Modern Lovers (August 1976).
By late 1973, Richman wanted to scrap the recorded tracks and start again with a mellower, more lyrical sound, influenced by the laid-back local music he had heard when the band had a residency at the Inverurie Hotel in Bermuda earlier in the year. These stymied efforts to complete a debut album led to the breakup of the original Modern Lovers in February 1974.
In 1975, Richman moved to California to record as a solo singer/songwriter with the independent Beserkley Records label.
In January 1976, Richman put together a new version of the Modern Lovers, which included original Modern Lovers drummer David Robinson, former Rubinoos bassist Greg 'Curly' Keranen and Leroy Radcliffe on guitar. The new group, now billed as Jonathan Richman and The Modern Lovers, found Richman turning away from the harder, Velvet Underground-influenced electric rock of the original Modern Lovers, toward a gentler sound mixing pop with 1950s rock and roll, and including a bigger emphasis on harmony vocals.
Richman's own songs continued to mix straightforward love themes with more whimsical themes like Martians ("Here Come the Martian Martians"), Leprechauns ("Rockin' Rockin' Leprechauns"), the Abominable Snowman ("Abominable Snowman in the Market"), and mosquitoes ("I'm Nature's Mosquito"). Richman's 1977 recording of the children's music standard "The Wheels on the Bus" made explicit his interest in making music for listeners of all ages.
The album Jonathan Richman and the Modern Lovers was released in May 1976, three months before the older The Modern Lovers sessions were finally released. Drummer David Robinson left the group soon thereafter, due to frustration with Richman's quest for lower volume levels, and joined with Ric Ocasek in forming the band the Cars.
After several months as a trio, Richman found a new drummer, D. Sharpe, an avant-garde jazz player on the Boston scene, who later went on to become a member of pianist Carla Bley's band.
