In the late 1970s and early 1980s, Allen recorded a solo piano album for the Pianocorder Contemporary Artists Series, joining such other artists-pianists of the day as Liberace, Floyd Cramer, Teddy Wilson, Roger Williams, and Johnny Guarnieri. His solo album was popular. Pianocorder was founded by Joseph Tushinsky. The Pianocorder was the first modern mechanical player piano made for the public that used solenoids to power the keys. Later, it was bought out by Yamaha Disklavier and discontinued and is known today as the Yamaha Disklavier.
