The Alien Cowboys third Bill Drescher-produced CD, Zero Gravity, is probably considered their finest work and features 12 new original instrumental compositions along with a four-song Beatle medley. Drescher is known for his work with Rick Springfield, Richard Marx, Ringo, Nick Gilder, The Tubes and more. Gary Cirimelli also contributed to Zero Gravity with an engineering/producer credit on the reggae-influenced, King of Kingston. A singer and guitarist himself, Cirimelli was a pioneer in the use of computers to record music. A chance meeting with Paul Reed Smith, who was just beginning what would become a major guitar design and manufacturing business, led to lead guitarist Ralph Perucci joining PRS Guitars as a field rep as well as Smith`s own band, the PRS Dragons. Paul shares lead guitar duties on Ralph`s song, "Jenna`s Eyes". Other guest guitarists appearing on the Zero Gravity CD include Austrailian guitarist and Santana protege, Orianthi, trading licks with Ralph on the title track, and Favored Nations` screamer, Johnny Hiland lends some serious heat to the track, "Lead Foot Rumble".
