Before joining Giuffria, Lanny was the main songwriter for his original bands named Lights, American Heroes and Mondo Cane with such songs as "All For One," "Lonely Money," "Blow It All Away," "Nasty Girl," "Gypsy in a Twisted World," "Dream Carnival," "High on a Dream," "Empty Cabaret," "Can't Wait Any Longer," "Uncontrolled Fire," "Prime Time," "(She's So) Photogenic," "Walking on the Edge," "Violent City" and "Riddles in the Night."
Both American Heroes and Mondo Cane gained their greatest success in Hollywood in the early 80s. Other contributing members of those bands included Bret Alstadt on lead vocals, Joey Leon on drums and Loren Robinson on bass guitar. Shawn Perry became Mondo Cane's manager in 1982 and Mark Lundquist, a keyboard player and backing vocalist, was added to the band in 1984. Robinson left and the band went through three other bass players before folding in 1985.
Lanny attended Cypress High School in Cypress, California and began his career by playing weekend parties in neighborhood garages and then branching out into the entertainment circuit by playing various clubs in Orange and Los Angeles night clubs. While "on tour" in the Southern California club circuit, Paul Shook (guitar technician) Brent Cobleigh (bass guitar technician) and Scotty Gustafski (drum technician) were the road crew for American Heroes/Mondo Cane. They went on to start to form their own band, Charade, rehearsing several of AH/MC's songs.
Lanny has made several solo albums, as well as being featured as guest musician, songwriter and/or producer on albums with artists like Ken Tamplin and Ransom. Besides the guitar, he also masters other instruments. In 2006, Lanny was a contributor of the Bulgarian rock group D_2 and especially their third album, 6.
Lanny has also appeared on the popular American television sitcom Full House, as a member of Jesse Katsopolis's band, Jesse and the Rippers.
