For folk music lovers, the Caltech campus...

For folk music lovers, the Caltech campus is the place to be this weekend. On Saturday, Scottish folk singer Jean Redpath, known throughout the world as an extraordinary exponent of her homeland’s traditional music, will perform.

Since Redpath’s first trip to America in 1961, audiences at folk festivals, Greenwich Village coffee houses, college auditoriums and formal music halls have become acquainted with her. She was a frequent guest on Garrison Keillor’s “A Prairie Home Companion� radio show in the 1980s. A Los Angeles Times reviewer once said of Redpath: “She is a wonder.�

The show will be at 8 p.m. at Beckman Auditorium on Michigan Avenue south of Del Mar Boulevard in Pasadena.

Then on Sunday, Virginia’s John McCutcheon will appear at 7:30 p.m. in Dabney Hall, near Wilson Avenue and California Boulevard. He is considered one of America’s leading revivalists of traditional Appalachian music.

During his concerts, he glides from instrument to instrument, stirring rich, moving sounds from fiddle, Autoharp , banjo, piano, guitar and hammer dulcimer.

Tickets for the Redpath concert are available from Ticketron outlets and the Caltech Ticket Office at 332 S. Michigan Ave. Prices range from $20 to $27.50. There is a $2 discount for people under 18, and special rush tickets for students and senior citizens will go on sale for $7.50 a half-hour before the show begins.

McCutcheon tickets are $12.50 each. Information for both concerts is available by calling (818) 356-4652.
