What is the name of the person that Carl Grasso invited to the Magic Castle?  Answer the above question based on the context below:  Following the Pixies' breakup, Lovering drummed with several artists, including Nitzer Ebb, but turned down an invitation to join the Foo Fighters. Lovering then joined Santiago's band The Martinis, appearing on their song "Free" on the soundtrack of Empire Records. However, he soon left the band to become a touring drummer for Cracker. Lovering moved from band to band, drumming with Tanya Donelly's group on 1997's Lovesongs for Underdogs and with Boston band Eeenie Meenie. After facing difficulty finding new work, Lovering gave up the drums and moved into a rented house that banned drumming.Towards the end of the 1990s, Lovering's friend Grant-Lee Phillips took him to a magic convention.

He shuns traditional magic tricks, and prefers "things that are more mental, using mental powers". He later explained: "It's all kind of upbeat, really weird physics experiments that you'll never see. [...] I'd rather have them [the audience] going 'Is it [magic] or isn't it?' rather than 'It's all science' or 'It's all magic'. So I do kinda weird things that other magicians don't do". Lovering cites sleight-of-hand artist Ricky Jay, mind reader Max Maven and Eugene Burger as influences on his technique. His performances often involve...
