Task: Question Answering
Input (English): Passage: Frusciante wrote and recorded a plethora of songs during and after the By the Way tour. In February 2004, he started a side project with Joe Lally of Fugazi and Josh Klinghoffer, called Ataxia. The group was together for about two weeks, during which they recorded about ninety minutes of material. After two days in the recording studio, they played two shows at the Knitting Factory in Hollywood, and spent two more days in the studio before disbanding. Later that year, five songs provided by Frusciante appeared on The Brown Bunny soundtrack.
Frusciante released his fourth full-length solo album Shadows Collide with People on February 24, 2004. This featured guest appearances from some of his friends, including Klinghoffer, and Chili Peppers bandmates Smith and Flea. In June 2004, he announced that he would be releasing six records over six months: The Will to Death, Ataxia's Automatic Writing, DC EP, Inside of Emptiness, A Sphere in the Heart of Silence and Curtains. With the release of Curtains Frusciante debuted his only music video of 2004, for the track "The Past Recedes". He wanted to produce these records quickly and inexpensively on analog tape, avoiding modern studio and computer-assisted recording processes. Frusciante noted, "These six records were recorded in a period of six months after coming home from touring with the Chili Peppers for one-and-a-half years. I made a list of all the songs I had and they totaled about seventy. My objective was to record as many songs as I could during the break that I had. In the midst of doing that, I was writing some of my best songs, so some of these albums have as many new songs as old songs. It was definitely the most productive time of my life.". 
Question: What are the last names of the people who recorded about ninety minutes of material?
Output (English): Klinghoffer.
